| 摘 要： | 研究了降低捕集剂镍用量的小铳试金铂族元素富集方法。通过测试，比较了重约０．５ｇ、２．５ｇ、２５ｇ试金扣的酸溶时间、铂族元素（ＰＧＥ）空白值。研究证明２．５ｇ试金扣既克服了常规试金扣和微型试金扣的缺点，又保留了它们的优点。经标准物质难证，铂族元素测定值与真值相符合。 |

| Abstract: | A method was developed for the determination of sub-trace platinum group elements (PGEs) by combination of inductively coupled plasma mass spectrometry and a fire assay with concentration procedure of about 2. 5 g nickel sulfide buttons. Through the comparison of different weight buttons, the procedure of about 2. 5 g buttons was selected. This method was applied to the determination of PGEs in geological reference materials except for chromite and their results were in agreement with the certified values. |
| Keywords: | Little nickel Sulfide fire assay platinum group elements inductively coupled plasma-mass spectrometry |
