Research Abstract

The chelating agent APCAs (Aminopolycarboxylic acids) are widely used, and as a result are showing up widely in the aquatic environment. To clarify the level of APCAs in water environment, we developed a preconcentration procedure for measuring APCAs concentration in water samples consists of various salinity by HPLC. A convenient HPLC method for quantitative determination of EDTA in foods was also developed.
