【摘要】 选定了混合熔剂的比例及用量,试样经半熔后制备成与淋洗液匹配的试样溶液,结合色谱条件的选择成功地将离子色谱法应用于硫化矿中高含量S和As的测定。含As 42.44％和含S20.97％的试样其相对标准偏差(n=8)分别为0.53％和0.47％更多还原

【Abstract】 The sample is sintered with a mixture of Na2CO3 and ZnO and prepared to make a solution to match the eluant. The method has been successfully appliedto the determination of high contents of S and As in sulfide ores, the relative standard deviations (n=8) were 0.47% and 0.53% for 20.97% S and 42.44% As, respectively.更多还原
