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.

螯合剂APCA（Aminopolycarboxylic Acids）被广泛使用，因此在水生环境中广泛出现。为了阐明水环境中APCA的水平，我们开发了一种预浓缩程序，用于测量水样中的APCA浓度，由HPLC组成。还开发了一种用于定量确定食品中EDTA的方便的HPLC方法。
