摘要
通过硫酸铅在不同浓度硫酸中的沉淀情况,缓冲溶液对硫酸铅沉淀的浸取效果及试剂用量等试验研究,提出了改进分析铅传统工艺流程的新方法及铅、锌连测,提高了分析结果的准确性和及时性。
Through experimental study on different precipitating states in different density of sulfuric acid ,the result of leaching precipitate of lead sulfate by buffer solution and the quantity of reagent used ,a new method to improve the traditional process flow to assay lead and simultaneously assay lead and zinc was put forward in this paper.The new method has improved the accuracy of the assaying result.
