The Use Of Detergents And Its Effects On The Environment

If bleach is used compared to the other detergents, then bleach will work best because it has the most whitening agent. The experiment will work around this hypothesis in hopes of proving it right using both the background knowledge and the experimental data. In the experiment bleach will be applied to 5 shirts along with tide, gain, oxy-clean, and arm and hammer in varying washes to see which detergents remove the stain applied by grape juice the best. *Note only

Take a look around your house and identify household products that work by means of an enzyme. Name the products, and indicate how you know they work with an enzyme.

Surfactants, also known as detergents, are molecules that have a non-polar end and a polar end. They can blend compounds that normally are not soluble in water alone. Substances that would normally stay separate in water will not when there is a surfactant mixed in with it. Phosphates are compounds that have a phosphate and an ionic charge. They work well against stains that have iron oxide in it.

The goal of this project was to make, and test four soaps, and two detergents. The purpose of making four different soaps and two detergents was needed in order to decide which one would be best for the environmental group to use in the future that would allow for the safest cleanup of an oil spill while not harming the animals or the environment in the process. It was necessary to test the impact of the four soaps and two detergents by analyzing their different properties based off of their specific characteristics and the wastewater left over from the vacuum filtration procedure. This procedure had to be undertaken in order to confirm which of the soaps and detergents synthesized is most

What effect did each of the contaminants have on the water in the experiment? Which contaminant seemed to have the most potent effect on the water?

Organisms cannot depend solely on spontaneous reactions for the production of materials because they occur slowly and are not responsive to the organism's needs (Martineau, Dean, et al, Laboratory Manual, 43). In order to speed up the reaction process, cells use enzymes as biological catalysts. Enzymes are able to speed up the reaction through lowering activation energy. Additionally, enzymes facilitate reactions without being consumed (manual,43). Each enzyme acts on a specific molecule or set of molecules referred to as the enzyme's substrate and the results of this reaction are called products (manual 43). As a result, enzymes promote a reaction so that substrates are converted into products on a faster pace (manual 43). Most enzymes are proteins whose structure is determined by its sequence of its amino acids. Enzymes are designed to function the best under physiological conditions of PH and temperature. Any change of these variables that change the conformation of the enzyme will destroy or enhance enzyme activity(manual, 43).

Following Figure 5 are the absorbance spectra of Rhodamine 6G under different surfactant compounds. Analogous to the previous calculations, the CMC of the detergent of interest can be determine by plotting the area of absorbance as a function of detergent concentration where the discontinuity on the plot indicates the corresponding CMC value, as shown in the Figure 6. Further, the comparison between the experimental CMC values with Rhodamine 6G and literature values are tabulated in Table 2 with the associated percent

The primary goal of the experiment was for the team to develop soaps and detergents to aid in clean-up of a hypothetical oil spill. The team had to determine which soap or detergent was the most effective at cleaning, as well as, which one had the least impact on the environment. To determine the desirables of the soaps and detergents, the team set out to determine the solubility of the starting materials in various polar and non-polar solvents.

Detergent tends to build up over time and you may find that one day the detergent cup won't open. The detergent acts like glue, sealing the cup. Your dishwasher's detergent cup is located on the panel, inside your dishwasher's door. Grab your sponge and a bucket of warm water and clean the detergent cup inside and out. If this doesn't fix your problem, read on.

Enzymes are biological catalysts which speeds up chemical reactions without being used up. There are three main factors which affect enzyme activity, and determines if their rate of reaction which are; sufficient energy (temperature), the pH, and the concentration. When there is a reaction, there must be energy around, the higher the energy, the faster the reaction because the particles will move faster therefore the chance of the particles to collide into each other will increase. However, if the temperature is too high or too low, the enzyme would denature and it will no longer work. This is similar to the pH; each enzyme will have a different optimal pH (a pH which an enzyme works best at) but if the pH is too high or too low, it will change shape and denature. Lastly as the concentration increases, so does the rate of reaction since more concentration means that there are more particles to react with. “To have a chemical reaction, there must be a least amount of energy which is called activation energy and enzymes help lower the activation energy therefore the speed of the reaction will increase”. People made wine for a long time without the help of enzymes in the winemaking process, but now pectinase is used around the winemaking society which enhances the process of wine making, however, there are limitations to use this enzyme. In this essay, the conditions that pectinase will need to be in will be analysed, and it’s affects economics and society.

In today’s society chemicals, whether you like it or not are a fact of life. Many people are afraid of chemicals and their effects on them and the environment. This is understandable because the truth of the matter is that chemicals can do some horrible things to humans, animals and the whole ecosystem. Some would say that chemicals should be done away with for these reasons. But this certainly is not true and most likely impossible. Chemicals can also have some very positive effects on our lives. Some uneducated people would argue that there should not be restrictions on chemicals. This is just as crazy as saying that chemicals should be done away with. If chemicals are regulated and people abide

The disposal of untreated wastewater coming from the industries into the water bodies will pollute the water bodies because of its high concentrations. So, the wastewater produced from the industry should be treated properly to meet the permissible limits given by central and state pollution control boards. Therefore it is necessary to treat the wastewater properly with the help of an appropriate treatment plant. However, the treatment plant even though properly planned may not work satisfactory because of several reasons. Hence, it is essential to evaluate the treatment plant considering individual treatment unit in the entire treatment flow. In the present work emphasis has been given to the study of the performance of treatment facilities because of its importance in the conventional treatment of wastewater. Hence, the literature review related to the evaluation of the entire treatment process along with biological treatment process particularly suspended growth process Activated Sludge Process (ASP), attached growth process Trickling Filter (TF) and a combination of the both suspended and attached growth process Hybrid Reactor (HR) is presented in the following sections of this chapter.
