Earth’s freshwater supplies are at risk of being contaminated beyond what is safe to drink. People’s activities on the ground can have a significant impact on the quality of earth’s freshwater supply.
Despite the best efforts of these companies to manage their solid waste, industrial and trash from manufacturing companies could end up in the water supply. The water system could be contaminated by organic and inorganic wastes such as plastic bags, empty containers, or other organic materials.
These types of wastes are easy to separate by physical means. There are microscopic wastes, however, that are not visible to the naked eye. These are the types of waste that cannot be separated physically. To identify them, one must use chemical processes like paperchromatography.

Water Quality Contamination Sources
Water from aquifers, streams, lakes, rivers and other fresh water sources do not contain pure water. These water sources also contain biological and chemical components that occur naturally, including algae, phosphorus and nitrogen.
These essential elements are vital for maintaining healthy freshwater ecosystems. These freshwater systems have been harmed by human activity. The freshwater systems have been contaminated by pollutants from homes and businesses.
These are the most common sources for freshwater pollutants:
The most prevalent contaminants in drinking water are pharmaceuticals. One survey revealed that 53 of the 74 locations tested positive for pharmaceutical contaminants.
Most commonly found in water is estrogenic hormones, which are contraceptive drugs.
Antibiotics and Nicotine. Other contaminants that can enter the drinking water supply include nicotine-laced urine, which is a result of heavy smoking, and antibiotics from the urines of farm animals.
There are many chemical methods that can be used to assess the quality and safety of drinking water. Paper chromatography is one of these methods.
What is Paper Chromatography?
Paper chromatography is a method that chemists use to determine the chemical composition of a solution. It involves separating individual components. The solution is then placed on a strip made for chromatography. The strip of paper is then coated with a solvent.
The solubility of the mixture to be separated will determine the type of solvent that is used. Water, oil, and alcohol can all be used as solvents by chemists. The solvent is able to carry the various component molecules with it as the solvent runs up the paper.
This allows you to see individual colors of the molecules on the paper.
Water Quality Analysis
The paper chromatography method is useful in analyzing the quality and composition of various mixtures. It can be used by chemists to determine the amount of drugs in the drug.
Chemists can use paper chromatography as well to analyze water quality. This involves identifying and seperating any impurities in the water sample.
Other Paper Chromatography Applications
Paper chromatography is more than just identifying the colors used in school markers. Paper chromatography is useful in many different areas.
Purification and Isolation:Chemists also have the option to use paper chromatography in order to separate the substances from a mixture. Because solvents carry different solutes at different rates you will be able to identify the location of the solute within the paper chromatography.
To obtain a pure sample, you can cut it and then dissolve it in appropriate solvents until you get a purified sample.
Forensic Science & Pathology:Paper Chromatography is also useful in solving crimes by forensic chemicalists. Paper chromatography can be used to analyze samples taken from crime scene scenes. For example, paper chromatography can be used to analyze blood samples from crime scenes for foreign chemicals like alcohol or poison.
Food Quality MonitoringChemists can also use paperchromatography to determine if food products are containing prohibited ingredients. Paper chromatography can also be used for analyzing the nutritional content of certain foods.
Don’t think of paper chromatography experiments as something you did as a child to only amaze you with science. Paper chromatography can be useful in many areas.
