Abstract – Removal of synthetic dye (methylene blue) from aqueous solution was studied using agricultural and plastic wastes based carbons. So the objective of present work is to propose an alternative use for agricultural and plastic wastes which are commonly available wastes. For the removal of methylene blue (MB) from aqueous solutions batch experiments were carried out. The operating variables like temperature, adsorbent dose, initial dye concentration

PROXIMATE ANALYSIS
3.2.1. Moisture content-
For calculating moisture content, sample taken in a petri dish was placed in the hot air oven at 1000C for one and half hours. Later it was taken out and weighed. Moisture
3.2.2. Ash content-
Sample taken in a silica crucible was ignited in the muffle furnace at 6000C for one and half hour. After the time span, it was taken out from the furnace and weighed.
3.2.3. Volatile Matter-
A known amount of sample was taken in a cylindrical crucible. The crucible was placed in a muffle furnace at 9250C, covered with lid, and heated for exactly 7 minutes. Then it was taken out, allowed to cool and weighed.
3.2.4. Fixed carbon content-
The fixed carbon content was determined by subtracting sum of percentage compositions of moisture , volatile matter and ash content from 100.
Fixed carbon FC=100-(volatile matter + ash content)

Procion Red Dye Lab Report
1454 Words | 6 PagesFor 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.

1366 Words | 6 PagesThen more roasting occurred when the crucible was placed into a ceramic triangle for the Bunsen burner to continue its burning for an additional 90 minutes. Once the burning was officially over, the crucible was placed onto a ceramic tile to cool off. Next the charcoal and copper material were poured onto a paper towel and were separated from carefully distinguishing them one from the other. Then comparisons were down through analysis of the copper (II) oxide smelted.
6.03 Calorimetry Lab
775 Words | 4 PagesIn the first part of the experiment, Part A, the standard solutions were prepared. As a whole, the experiment was conducted by four people, however, for Part A, the group was split in two to prepare the two different solutions. Calibrations curves were created for the standard solutions of both Red 40 and Blue 1. Each solution was treated with a serial 2-fold dilution to gain different concentrations of each solution.
Millsaps College Lab Manual
1232 Words | 5 PagesMETHOD: The following procedure was taken from the 2017 Millsaps College lab manual.1 The experiment was split into two parts, part A and part B. Part A was to find the heat capacity while part B determined the specific heat of an unknown metal. This was the final goal of the lab. To start, a temperature probe had to be connected to a LabQuest2 data collection device. 100.0 mL of deionized had to be added into a Styrofoam cup.
The Crucible: Three Boiling Chips
292 Words | 2 PagesNow, they are ready to start the lab. The empty crucible is weighed by and the weight was recorded. Then the students used a disposable pipet and put close to 4.0 grams of their milk sample in their crucible on the scale. The crucible was then placed back on
Unknown 6 Essay
680 Words | 3 PagesCharacteristic Property- Test 2- Density Materials: Triple Beam balance, distilled water, graduated cylinder, unknown 6 Procedure: first we found the mass of the empty graduated cylinder and then its mass with the now distilled unknown. After subtracting the mass of the graduated cylinder, we were able to find the volume. For every 1mL=1cm³ so there we had the volume found with the graduated cylinder. We divided the mass by the volume in order to get the density Data: We found that the density of our unknown was 0.76 g/cm3.
Hydrates Lab
737 Words | 3 PagesThen an estimated (by trial and error) 1-3 grams of hydrated copper sulfate was added to a crucible with the lid on top. The total mass of the hydrated copper sulfate was recorded by subtracting the total mass of the crucible, lid, and sample from the mass of the crucible and lid (described in table 1.3). By attaching the wire triangle to the ring, the crucible was able to sit securely while having the bunsen burner underneath. Lighting the burner once again, each substance was heated for several minutes until estimated that the compound had changed color. Once a prevalent color change had been observed at approximately 4 minutes (blue green color) the crucible was set on the counter using the tongs to cool for approximately 5 minutes.
Rapid Oxidation Of Steel Wool Lab Report
1278 Words | 6 PagesThe aluminum foil and the steel wool were taken outside onto a concrete driveway and ignited using a match. As the steel burned, I blew on the steel wool to make sure all the steel wool was consumed. I made sure that I did not blow too hard and scatter the combustion products. After making sure that the fire was out and all the fuel was consumed, I brought the aluminum pan now containing the combustion product inside and allowed it to cool to room temperature. Once the aluminum pan and combustion material reached room temperature, I weighed the pan.
Average Concentration Lab Report
597 Words | 3 Pages(1) If the crucibles were not put in the oven at the end of the experiment, there could be excess moisture trapped in the crucible. This contributes to the mass of the weighed crucible at the end of the experiment, meaning the mass would be higher than it would normally be. After calculations, it can be concluded that the moisture in the crucible shifts the data up, creating an artificially high concentration of Al3+. (2) Reading the volumetric pipet to 25.00mL is an incredibly crucial step in this experiment because it’s the only source of Al3+ that is added to the reaction. This step affects the end result when weighing the precipitate because in the reaction, the Al3+ is the limiting reagent and is in a 1:1 stoichiometric ratio with the precipitate product.
Water Of Hydration Lab Report
407 Words | 2 PagesAfter we put the substance on the burner, we weighed it. Each time after we put it on the burner came with the exact same number: 21.16 grams. After we found the mass of the crucible, cover, and hydrated sample, and the mass of the crucible, cover, and dehydrated sample, we subtracted the two values to get the mass of water evolved: 0.24 grams. Then, we subtracted that value to the mass of the hydrated sample to get the mass of the dehydrated sample: 0.76 grams.

1572 Words | 7 Pages3mL of the liquid in each of the vials were added into cuvettes and measured in the spectrophotometer. Before each time point the photo spectrometer was zeroed using a cuvette with 3mL of distilled water. If any of the results were considered unusual the machine was zeroed again and the sample was retested. The results from the spectrophotometer test were recorded in a table. The experiment was repeated six times to gain a sample size of six.
