Open publisher page 0 citations

Abstract

A new complex chemiluminescence system, i.e., luminolH\-2O\-2 catalyzed by CoHR\+- complex is reported. Based on this catalyse a new chemliuminescence method for determining trace of Co() is proposed. The detection limit is 1.2910\+-9 g/L Co(), the linear dynamic range is 510\+-8110\+-5 g/L Co() and the variation coefficient at a cabalt concentration of 110\+-7 g/L Co() is 2.5 % (n=5). This mettod has been applied satisfactorily in the determination of trace cabalt in waste waters.
