| 摘 要： | 本项工作试图利用等离子光谱分析的特点,制定一个用样量少,分析速度快,分析成本低和测定元素多的黄铁矿单矿物分析方法。由于黄铁矿单矿物中铁的干扰严重,几项易挥发元素的检出限较差,所以还需保持必要的取样量。 实验部分 1.工作条件 光量计:Jarrell—Ash Mark Ⅲ 1160 Plasma ATOMCOMP 雾化器:高盐雾化器,附蠕动泵。

A Study on The Analysis of Pyrite Minerals by ICP-OES |
| |
| Abstract: | This study deals with the use of plasma direct reader for simultaneous mul-
tielement analysis of pyrite minerals. 100mg of sample was dissolved in nitric
acid and filtered. 11 trace elements iron (mostly are volatile) in the filtrate,
which were suffered from iron interference were determined after passing thro-
ugh cation exchange column. Filtered residue was attacked by either method
depending on demands. (1) HN03+HCl ( 3+1) was used for pure pyrite and (2)
alkali fusion was used when total contents of aluminum, titanium and tin were
required. The resulting solution was combined with the eluted solution of some
other 17 elements retained on the column and then analyzed in a separate pro-
cedure. |
