Chelate reagent and measuring aluminum and measuring method

摘要

A chelate reagent containing an analytical chelating agent for measuring aluminum to be used in a method of measuring the amount of aluminum contained in a sample which comprises forming a complex of aluminum in the sample with the analytical chelating agent under such conditions that the equivalent concentration of the analytical chelating agent in the liquid reaction mixture is 6 times or more as high as the conventional level and then chromatographically detecting the complex. By using this reagent, the content of aluminum in a sample can be conveniently and highly accurately determined chromatographically without affected by any interfering substances.
