Chemiluminescence of Luminol-K_2S_2O_8-Ni(SAA)_2~(2-) System and Its Application

Zhi Xuan-hao

Abstract

This paper reports a new complex chemiluminescence,i.e,luminol-S 2 O 8 2- catalyzed by Ni(SAA) 2 2- complex.Based on this catalyse a new chemiluminescence method for determining trace of Ni(Ⅱ) is proposed.The detection limit is 0 103μg/L Ni(Ⅱ).The linear dynamic range is 1～100μg/L Ni(Ⅱ).The relative standard deviation is less than 2 1%(n=5).The method has been applied to determination of trace nickel ion in polluted waters.
