Abstract

A rapid, simple, and accurate method of determining concentrations of Fe-chelating agents in solution was developed. The assay employs Cu-CAS (chrome azurol S) complex as a testing agent and measures the equilibrium concentration of this complex in the presence of other Fe chelators. The Cu-CAS was found to be advantageous in comparison to other compounds. This method is of particular importance for colorless chelates, which are very difficult to determine otherwise. -from Authors
