| 摘要: |
| 采用高频红外吸收法测定硫化锑精矿和氧化锑精矿中的硫含量。确定出最佳分析条件是用1.50g钨粒+0.50g锡粒+0.60g纯铁作助溶剂。硫化锑精矿称样量为0.00500g,氧化锑精矿称样量为0.20000g,分析时间以65s较为适宜。RSD(硫化锑)=1.31%(n=8),RSD(氧化锑)=2.03%(n=8)。 |

| Abstract: |
| The method of high frequency IR-absorption spectrometry used to determine the sulfur in antimony sulfide concentrates and antimony oxide concentrates is introduced in this article.By this method the best analytical conditions determined are that the dosage of flux is 1.50g of tungsten granular、0.50 g of tin granular and 0.60g of pur iron filings,the sample weight of antimony sulfide concentrates and antimony oxide concentrates is 0.00500g and 0.20000g,the analysis time is 65s.The relative standard deviation of antimony sulfide concentrates and antimony oxide concentrates was 1.31% and 2.03%(n=8). |
