| Abstract: |
| 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. |
