Abstract
A simple method has been developed for the separation by high-performance liquid chromatography of some common aminocarboxylic acid sequestrants as their copper complexes. The copper complex is formed in situ by using a copper salt solution as the eluate. Detection using visible light at 760 nm eliminates interference from ultraviolet absorbing compounds often present in mixtures containing sequestrants.Keywords
