Abstract

The selective effect of triethylenetetramine (Trien) on the retentionbehavior of sulfate in ion chromatography was studied. When Trien wasadded to an eluant as a counter ion, retention of sulfate was selectively shortened, while retention times of monovalent anions did not change. The cause for this phenomenon was the complexation of sulfate andTrien in an eluant. The stability constants of divalent sulfate-trivalent Trien and -tetravalent Trien complexes were estimated to be 936 and 4213 (40-degrees-C), respectively. As a practical application of this phenomenon, weakly retained monovalent species can be very well separated from both water dip and other species without prolonging the interval of injections.
