摘要研究了腐殖酸、Triton X-100和红葡萄酒对Cu（Ⅱ）和Pb（Ⅱ）阳极溶出伏安法和计时电位溶出分析（CPSA）中沉淀和溶出步骤的影响。富里酸和Triton X-100只对剥离步骤有影响;腐殖酸和红葡萄酒影响这两个步骤。未能确定基质组分对单个沉积和剥离步骤的影响可能导致对金属离子形态的错误解释。
Abstract The influence of humic substances, Triton X-100 and red wine on the deposition and stripping steps in anodic stripping voltammetry and chronopotentiometric stripping analysis (CPSA) of Cu(II) and Pb(II) was investigated. Fulvic acid and Triton X-100 had an impact only on the stripping step; humic acid and red wine influenced both steps. Failure to establish the impact of matrix components on the individual deposition and stripping steps could result in erroneous interpretation of metal ion speciation.
