Within these two broad categories, APIs can also be further classified based on their chemical nature. There are natural APIs, which are derived from plants, animals, or minerals. Examples include morphine from opium poppy and digoxin from foxglove plants. Semi-synthetic APIs, which are chemically modified derivatives of natural substances, also play a crucial role. An example is the antibiotic amoxicillin, a derivative of penicillin that is more effective against a range of bacteria.
Water treatment plants play a pivotal role in ensuring that the water we consume is safe and free from contaminants. Among the various processes employed in these facilities, chemical treatment is a crucial component. Two widely used chemicals in water treatment are chlorine and alum, each serving distinct yet essential purposes in the purification process.
