摘　　要：针对线性扫描极谱法在线同时分析湿法炼锌浸出液中多金属组分时亟待解决的重叠峰分离难题,提出了一种新的分离此类重叠峰的方法。通过深入研究极谱波的产生机理,采用非线性加权最小二乘法对重叠峰进行拟合,获得待分离峰重构参数的精确值,并以此重构参数为基础,将重叠峰分离为独立子峰。实验结果表明,该极谱波模型具有很好的极谱峰描述能力与准确的分辨能力,能够快速,准确的实现极谱重叠峰分离。For linear sweep polarography online and analysis of wet zinc smelting leaching liquid,a new method of separating such overlapping peaks was proposed. Through in-depth study of the mechanism of production of polarographic wave of the overlapped peaks by nonlinear weighted least squares fitting,for separation peak reconstruction parameters accurate value,and based on these reconstruction parameters,the experimental results showed that the polarographic wave model had better ability for polarographic peak description and accurate resolution,can quickly and accurately realize the overlapping polarographic peak separation.
