Phosphotungstic Acid Application
Phosphotungstic acid can be used in various biological alkali, nitrogenous base, phenol, protein, peptone, amino acids, uric acid, urea, blood and carbohydrates. Also being used in mass organic synthesis reaction catalyst.
Phosphotungstic acid hydrate agent mainly includes chromatography reagents and biochemical reagents, used to separate medicine, appraisal, and toxicology studies of chemical poisons, medicolegal expertise and analysis of biological material. It is also used as precipitants, oxidants and color agent, precipitants and oxidation, such as analysis atropine, aminopyrine, quinine, procaine and cocaine. Besides that, use thin-layer chromatography to detect steroids, ethanol phosphotungstic acid is needed. By analyzing the generating phosphotungstic acid testing result, phosphorus contained pesticides of fruits, vegetables, plants and foods can be identified.
