摘要
研究了温度对微分电位溶出法测定铜、锌、铅、镉的影响,15℃-50℃之间Pb、Cd、Zn溶出峰高稳定,铜的溶出峰高随温度升高而增高。解决了Cu在较弱酸性条件下被基线饱和区掩盖不易测定的问题。
This paper is concerned with effect of temperature on the indirect differentiation potentiomic stripping determination of Cu.Pb,Cd,Zn,between 15℃ to 50℃, the peak of Pb,Cd.Zn is steady. The peak of Cu is high as the temperature is high. This paper resolves the matter that Cu is undeterminable in weak acid conditions.
