這兩天看一篇文章 題目叫 XRS analysis of sulphides by fusion methods 文章出處:X-Ray Spectrometry Volume 19, Issue 2, pages 67–71, April 1990 摘要:A method is described for the XRS fusion analysis of mineral and plant concentrates containing sulphides (e.g. PbS, ZnS, CuFeS2 and FeS2) together with slags, mattes, fumes and drosses. The method involves a short pre-oxidation treatment using sodium nitrate, followed by fusion with an appropriate heat source. Losses of S by volatilization and of metals into the platinum crucibles are acceptably small for general assay purposes. 看了半天也沒看到XRS 的全名,請教一下XRS 代表的含義? |
