摘要
本研究在对传统分析方法进行总结、优化的基础上,提出了采用20%NaCl作为铅矾的浸取剂代替传统的25%NaCl的新方法,可大大减少背景的影响。采用3%HAC-15%NH4Cl-1.5%NH2HCl作为铅的氧化物的浸取剂,使得测定结果更精确、更接近实际值,因此该方法具有较大的推广应用价值。
Based on summary and optimization of the conventional analyzing methods, new and more accurate methods were put forward for chemical phase analysis of lead in this paper. 20 % NaCl took the place of 25 % NaCl as the extractant of anglesite, greatly reducing the effect of background on the experiment results; and by using 3% HAC-15% NH4Cl- 1.5% NH2HCl as extractant of lead oxides, making the analysis results more accurate, These methods are of wide application.
