摘要
Cu2+对鲁米诺-铁氰化钾碱性体系的化学发光具有较强的增敏作用,据此建立了流动注射化学发光法检测Cu2+的新方法.该方法具有简单、快速、线性范围宽等优点.测定Cu2+的检出限为8.0 10-10mol/L,线性范围为1.0 10-9~1.0 10-4mol/L,测定1.0 10-5mol/L Cu2+的相对标准偏差为1.2%(n=8).
A novel flow injection chemiluminescence method for the determination of CU^2＋ is developed based on the enhancing effect of Cu^2＋ on chemiluminescence of luminol-potassium ferricyanide. The method is simple, rapid and has wide linearity range. The detection limit of CuE＋ is 8.0~10^-10 mol/L in linearity range of 1.0× 10^-9-1.0×10^-4 mol/L. The relative standard deviation is 1.2% to the determination of 1.0×10^-5 mol/L Cu^2＋（/,/=8）.
