【摘要】 于铜离子对鲁米诺-铁氰化钾体系有催化化学发光反应的特性,采用毛细管电泳-化学发光法成功实现了对Cu(Ⅱ)的分离检测,并对化学发光条件和电泳条件进行了优化。在优化条件下,Cu(Ⅱ)的检出限(S/N=3)为7.5×10-9mol.L-1,线性范围为7.5×10-8-5.0×10-5mol.L-1,迁移时间和峰高的相对标准偏差(n=5)分别为2.9%、4.7%。更多还原

【Abstract】 Based on the fact that Cu2+ can catalyze the chemiluminescence(CL) reaction of Luminol with potassium ferricyanide,a novel capillary electrophoresis with CL method was developed for the determination of Cu(Ⅱ).Under the optimum conditions,the detection limit(S/N=3) for Cu(Ⅱ) was 7.5×10-9 mol·L-1,with the linear range of 7.5×108～5.0×10-5 mol·L-1.The RSDs(n=5) for migration time and peak height were 2.9% and 4.7%,respectively.更多还原
