molybdophosphoric acid spectrophotometric determination

Interactions between food dyes and metal ions may change their stability, toxicity and other physico-chemical properties of both metal and the dye. The toxicological evidence for synthetic colorants has led to reviewed safety of several compounds in most countries (Marmion, 1991). Accordingly, it is important for human health to know these complexes.
