鲁米诺－亮绿SF－过氧化氢－铜（Ⅱ）化学发光体系的研究

Study on Chemnuminescent System of Lu-minol-Light Green SF-peroxide-Copper(Ⅱ)

本文报道了鲁米格亮绿ＳＦ－过氧化氢。铜（Ⅱ）化学发光体系，建立了测定微量铜的化学发光新方法。相对标准偏差为２．４％（ｎ＝１０），检出限为１．６×１０￣－９ｍｏｌ·Ｌ￣－１。用于人发、茶叶及铜精矿样品中微量铜的测定，结果令人满意。

chemiluminescence(CL)system of lumi-nol-light green SF-peroxide-copper(Ⅱ)is re-ported. A new method of CL for the determi-nation of micro amount of Cu( Ⅱ )is proposed.The detection limit is 1.6 × 1O￣-9 mol/L,andthe RSD is 2.4%,This method can be appliedto the determination of copper in hair,tea,se-lected copper are with satisfactory results.
