Aluminum is a major element that constitutes zeolite molecular sieve. Its content and its distribution in molecular sieve framework directly affect the application and performance of molecular sieve. Therefore, it is of great importance to determine the content of aluminum in it. Absorbance spectrophotometric determination of aluminum has the advantages of simple and quick, the photometric method of aluminum literature [1] has been reviewed. Arsenazo (ASAI) is a rare earth element chromogenic agent, this article discusses the reagent with Al ()
