    摘要: An analytical method for determining aluminum in amino acids such as glycine. A complex of aluminum and dihydroxyazobenzene is formed by reacting the amino acid solution with a mixture of dihydroxyazobenzene and acetonitrile in the presence of a buffer to obtain a pH of between about 7 and 8. The resulting complex is analyzed for aluminum by high performance liquid chromatography. Minimization of aluminum contamination is achieved by reducing the number of reagents used in the procedure.
