1.1 Industrial Wastewater Pollution
In recent year due to the development in many industries such as light and heavy industries, it bring the higher potential effect to the environment. Even thought, these industries can give the benefits to the economy around the world, but the creation of the pollutant from these industries will produce the large amount of waste that harmful to human and environment. There are many kind of pollution likes water, air, noise and soil pollution that come out from the increasing of development industries. Water pollution one of the serious problem that arise where it can give biggest impact to the human, environment and other living thing as the water is a basic need for human, animals and plant.
Water pollution is the serious ecological threat that should to be overcome as well as to reduce the pollution. The toxic substances dissolved in the water bodies like oceans and rivers caused the water become more polluted and will degrade the water quality as well. In other hand, the contaminated water also will hazardous to the human health as the water is

As the textile industry is widespread over the world, the reactive anthraquinone dyes which are the second largest class after the azo dyes of textile dyes are used in this industry because of their application is easy while the energy consumption is minimal and the wide array of color shades (Aspland, 1997) will give the attraction to the users. The Reactive Blue 19 (RB19), also known as Remozal Brilliant Blue are the aromatic anthraquinone structure which is highly stabilized by resonance, whereas it is very resistant to the chemical oxidation. In the particular case, RB 19 is actually has the lowest fixation efficiency (75-80%) because of their competition between the formation of the reactive form and the hydrolysis reactions (Lizama et al., 2002;Pelegrini et al.,
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.
That mixture was then filtered through a coffee filter. Nine test tubes were prepared in order to perform this dye coupled reaction. One contained 5.0ml of the potato and pH buffer mixture, 2.0 ml of hydrogen peroxide, and 1.0 of guaiacol to serve as a blank for the spectrophotometer. Four test tubes were filled with 2.0 ml of hydrogen peroxide and 1.0 ml of guaiacol, used for measurement by the spectrophotometer, each. The last four were filled with 4.0 ml of the potato and pH buffer mixture and 1.0 ml of peroxidase.
The sunset yellow dye had a faster and more linear reaction time than allura red; this could be caused by incorrect dilutions of the dye and
The hypothesis that was provided to this question was If Phenol Red is add with the other chemicals then a color change will occur. Methods: To begin the lab 40 mL of Phenol red were obtained in a beaker, and 40 mL of water were obtained in a separate beaker. Next one plastic baggie was
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.
Method In this experiment, we tested our hypothesis through the use of chromatography paper. Chromatography paper have the ability to separate colored chemicals or substances. We also used 10 grams of grinded coleus leaves and grass leaves, 90% acetone, magnesium sulfate, pencil, ruler, forceps, 1 capillary, 1 jar with lid, and a timer to conduct this experiment. We began this experiment by grinding the 10 grams of coleus leaves and grass leaves in 10mL of 90% acetone.
Drinking contaminated water can cause different types of cancers and also infertility and birth defects due to of the presence hazardous chemicals. Impoundments that have not been built or properly closed off have led to the death of many animals and also health issues in
The purpose of this laboratory experiment was to identify the molarities of dye present in green Powerade and then create a solution that possessed the same concentrations. This experiment consisted of two parts of experimentation, the first part focused on identifying the dyes present and at what concentration, and the second part focused on the recreation of the stock solution. To successfully complete this experiment, a small cuvette, full of 2 mL of green Powerade, was placed into a UV spectrometer in order to identify which wavelengths were being absorbed and reflected. With this information a complete series of dilutions using yellow #5 and blue #1 dye in ratios of 1:1, 1:2, 1:3, 1:4, and 1:5 were conducted to find the max peak absorbancy
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
Although the pollution responsible for these statistics comes from a multitude of factors, there are four main industries which are contributing to the destruction of the environment which we would like to focus on; farming, mining, sweatshops, and e-waste
The first synthetic dye, Mauveine, was accidentally discovered by William Henry Perkin in 1856 while he was looking for a cure for malaria. Different dyes are made of different dye molecules. Dyes have colour because they absorb light in the visible spectrum (400–700 nm), have at least one chromophore, have a conjugated system (a structure with alternating double and single bonds), and exhibit resonance
Water Pollution is a huge environmental problem that has serious effects on marine habitats, animals, and water quality. BP1: The world's marine habitat has been getting worse because of how bad the pollution has gotten. “ Over 80% of marine pollution comes from land based activities “ (source 5 ). This quote explains how most of the water pollution is caused by human activity. “ Plastic litter does not degrade, can be expected to last in the oceans for hundreds of years “ ( source 6 ).
Bromination is a type of electrophilic aromatic substitution reaction where one hydrogen atom of benzene or benzene derivative is replaced by bromine due to an electrophilic attack on the benzene ring. The purpose of this experiment is to undergo bromination reaction of acetanilide and aniline to form 4-bromoacetanilide and 2,4,6-tribromoaniline respectively. Since -NHCOCH3 of acetanilide and -NH2 of aniline are electron donating groups, they are ortho/para directors due to resonance stabilized structure. Even though the electron donating groups activate the benzene ring, their reactivities are different and result in the formation of different products during bromination.
Water pollution is a serious issue as not only is water the most precious natural resource, but all sources of water support life that is very necessary for the survival of the planet. Water pollution destroys life and ecology and such damage is irreparable. Those who are still not serious about water pollution must also remember that the pollutants present in water not only destroy the life in the rivers and oceans, but also affect our food chain. Many people have the wrong notion that since they are not disposing the pollutants in the water they are not to blame. These people forget that 70% of the earth is covered by water, and any activity on the land can wash to the seas and oceans.
• Pollution: Pollution of air, water and soil require millions of years to recoup. Industry and motor vehicles exhaust are the number one pollutants. Heavy Metals, nitrates and plastic are toxins for pollution. While water pollution is caused by oil spill, acid rain, urban runoff; air pollution is caused by various gases and toxins
