High purity of organic chemicals is often a pre-requisite for industries with stringent quality standards. Organic acids (such as formic acid, fumaric acid, acetic acid, propionic acid, succinic acid, oxalic acid, lactic acid, malic acid, benzoic acid, etc.) and amino acids (such as methionine, lysine, tryptophan, aspartic, phenylalanine, etc.) often have undesirable colour impurities which can be removed by treatment with powder activated carbon. And, recycled dry cleaning solvents contain colour and odour compounds which can also be treated with powder activated carbon.
