Copper(II) complexes of cyclic tetra-azatetra-acetic acids-unusual features and possible analytical applications.
An examination of the copper(II) complexes of some cyclic tetra-azatetra-acetic acids has shown that the 1,4,7,10-tetra-azacyclotridecane-N,N',N'',N'''-tetra-acetic acid complex has an unusually high molar absorptivity and other favourable characteristics which make this ligand a convenient reagent for the fast and easy spectrophotometric determination of moderately small quantities of copper.
