摘要
探讨了吡咯烷二硫代氨基甲酸铵(APDC)及其氧化产物(DPTD)共沉淀富集-火焰原子吸收分光光度法测定食用盐中微量铅含量的最佳条件,线性及回收率满意。
This paper discusses the microanalysis method of lead ions in edible salt with both the concentration way of lead by precipitating via adding the chemical agent APDC and its oxide ramification DPTD and the next atom absorb determination step, and its optimum application conditions are also introduced. The results show this method is statisfied.
