For this lab, zeolite and magnetized zeolite were synthesized and compared with charcoal to find out with would be the most effective in the sequestering of Procion Red dye. Finding the concentration and absorbance of each zeolite, magnetized zeolite, and charcoal, along with a calibration curve, the best adsorbent is determined. Charcoal was the overall best sequestration of the Procion Red dye, since the adsorbent was highest compared to the others. Introduction Pollution has increased in the environment over the years, so the purpose of this experiment is to find the best adsorbent of chemicals to reduce the pollution. Zeolite and magnetized zeolite are synthesized and with charcoal they are used to find which will adsorb Procion Red MX-5B …show more content…
A hot plate was placed under the ring stand. 50 mL of 3.0 M NaOH in a 250 mL beaker and a stir bar was placed in the beaker. The beaker with NaOH was placed on the hot plate and 3.75 grams of NaAlO2*5H2O was placed in the beaker. The temperature probe was placed in the beaker with the solution, not touching the bottom of the beaker. The solution was heated and stirred till the solution dissolved. While the solution dissolved, 50 mL of distilled water was added to a 150 mL beaker and heated on the hot plate. When the solution started to boil 2.65 grams of Na2SiO3*5H2O was added to the beaker with a stir bar and heated to a gentle boil. When both solutions began to boil, the sodium silicate solution was slowly added to the sodium aluminate. The solution was kept at 900C for 60 minutes and stirred with stir bar. After 60 minutes, the zeolite solution was cooled for 5 minutes and for the magnetized zeolite , 0.78 grams of FeCl3 and 0.39 grams of FeSO4*7H2O was added to the flask and stirred until the iron parts dissolved. The magnetized zeolite was then cooled for 5 minutes. For both zeolite and magnetized zeolites, the solutions were placed in two centrifuges with equal amounts of solution and placed in both tubes. The tubes were placed in the centrifuge for 10 minutes at 5000 rpm. The liquid in the tube after the centrifuge was poured into a 200 mL waste …show more content…
Both the Benzo(a) pyrene, example of PAH, and Procion Red MX-5B have thin, benzene ring structures and have flat molecules that allow for adsorption. The flat molecules can be adsorbed by zeolites through intercalations. Intercalation is done by Procion Red dye or the PAH getting stuck in between two other molecules of zeolites or charcoal. A difference between them both is that Procion Red dye has OH bond, sodiums, and nitrogens on the structure where the Benzo(a) pyrene doesn’t have any, but doesn’t have that big of an effect of adsorption. Both of these models do the job of adsorption with their similar

Fiona Young Ha Hoang and Joey Lu 12/11/15 Malik AP Chem 4th Prepare to Dye Introduction Chromatography is the separation of a mixture or substance by putting it in a solute with chromatography paper. Following with this lab, we take 3 colors of food dye (red, yellow, and blue) and test which solvent out of distilled water, acetone, ethanol, and 2-propanal would separate the molecules in the dyes the best.
The purpose of this experiment was to analyze the amount of green plants versus albino plants that were created in the F2 generation. The results of this lab would allow the scientist to either support or reject the accuracy of the punnett square probability. The probability of the punnett square is that about 3/4 of the plants would be green and 1/4 would be albino. The purpose of this experiment is to investigate the passing of genes from parents to offspring.
Question: Describe what happened to the original spot of plant pigment extract? The spot traveled from the faint line on at the tip of the chromatography paper and it then created bands of colors. The original color of the plant extract was a black color and the once it was immersed in developer four it then started to travel up the paper strip. How do your Rf values compare with those of your classmates? They were similar but some were different due to errors in the experiment.
The objective of this study was to test the phototactic response of Daphnia when exposed to red (>600 nm) and white light. A 30 x 2 cm clear acrylic mesocosms with a 10 cm counting area was filled with distilled water and 10 Daphnia. We counted the number of Daphnia that traveled to the lit counting area after 10 minutes. There were twice as many Daphnia in the lit counting area for the control (white light) compared to the experimental group (red light). The results showed that red light had a negative effect on the phototaxis of Daphnia.
The materials for the lab included: Sodium bicarbonate, acetic acid, large Erlenmeyer flask, balloon, small graduated cylinder, and an electric balance. The second step of the first experiment was to measure 10 mL of acetic acid in the graduated cylinder. Next, measure half a spoonful of sodium bicarbonate. To weigh the sodium bicarbonate it was placed in the flask and weighed, using the electronic balance. The weight of the sodium bicarbonate was recorded in a data table.
The technique heterogeneous photocatalysis belonging to advanced oxidation process have proved to be one of the most effective treatment methods for the removal of pollutants from wastewater. In this process strong oxidizing agent hydroxyl radicals are produced which oxidizes a wide variety of organic pollutants into innocuous end products such as carbon dioxide, water and mineral acids………
Photograph Description: Photograph 1, shown on the previous page, was taken after 20 drops of the crystal violet dye was added to the solution, and photograph 2 was taken after 40 drops were added. As seen in the pictures, only a faint ring of violet was visible around the coacervates. Photographs 3-5 were taken after adding a drop of 20% concentration crystal violet dye onto the side of a slide. Discussion
Introduction The purpose of this lab is to investigate the enzyme action of proteases in pineapple. Enzymes are biological catalyst which speeds up the chemical reaction without being used. Enzymes are protein that is folded into complex shape that allow smaller molecules to fit into them, and also speed up the chemical reaction. It does not get used in chemical reaction, so it can get reuse again.
Drapex 6.8, supplied by Galata Chemicals from Louisiana, was the ESO used. Boron triﬂuoride diethyl etherate, dimethyl benzyl amine, hexanoic anhydride (97%), n-hexanoic acid (99%) and n-octanoic acid (99%) were obtained from Sigma-Aldrich, USA, while sodium chloride and sodium bicarbonate were obtained from Fisher Scientiﬁc, USA and used as received. The AMC-2 catalyst was purchased from Aerojet Chemicals, California, US. Epon 828 (epoxy equivalent weight, EEW 185-192 g/eq. Hexion technical data sheet of Epon 828 issued September 2005) and Epon 1001F (EEW 525-550 g/eq.
Several adsorbent are qualified for this purpose. Activated carbon is the most popular adsorbent which used for water softening but it cost remains its main drawback . A large number of low-cost adsorbents have been utilized for ions removal . Recently, natural clay minerals (e.g. bentonite) [24, 25] and zeolite [21, 26] have been widely used as adsorbents for adsorption of ionic and molecular species from various water streams.
Highlights are a great way to add a little pizzazz to your style, but many women find their boss arguing that excessively bright highlights are too "excessive. " Don't let him take away the creative control of your hair: try some herbal replacements. They are less bright than chemical highlights, making them more acceptable to square bosses. Choosing Your Herbal Dye First of all, you need to choose the best herbal dye for your personal needs.
bedrock and soil. Chromium weathered from the rocks is deposited on the soil and groundwater. Chromium is also generated anthropogenically from various industrial processes which includes electroplating, leather tanning, wood preservations, manufacturing of dye, paint, paper, petroleum refining processes, metal finishing, alloysteel manufacturing, and lasers(Owlad et al., 2010). According to BIS (Bureau of Indian Standards) and USEPA the maximum acceptable limit for Cr(VI) in drinking water is 0.05 mg/L and total chromium (Cr(VI) and Cr(III)) is 2 mg/L(Jain et al., 2010).
Azo dyes have characteristic chemical structure that is called (azo) bond R-N = N-R'. Azo dyes are compounds consisting of a diazotized amine attached to an amine or a phenol and contain one or more azo linkages. Aromatic amines are essentially the products of azo dyes. Nowadays there are more than 3000 recognized azo dyes which are present in different industries such as textiles, paper, food, cosmetics, and pharmaceutical industries (Johnson et al., 1978). Currently, there are six azo dyes used as food colorants: allura red (red shade)
