增敏溶出伏安法测定防污漆中的有机锡含量

Determination of Organotin in Antifouling Paint by Anodic Stripping Voltammetry

通过先萃取后消化的方法将有机锡转变为无机锡,通过表面活性剂的增敏作用,使用方波溶出伏安法进行测定,此方法可快速、准确地测定防污漆中有机锡的含量.同时对仪器工作参数进行了优化,对底液的组成及浓度进行了选择,确定了最佳的分析条件.

The content of organotin in antifouling paint was determinated by ASV through melting the extraction of organotin, turning organotin into inorganic tin. And the CTMAB was used to improve the sensitivity of determination. The method is simple and rapid, and the electrolyze was selected and the parameters were optimized too.
