硫氰酸汞分光光度法测定矿石中氯

Mercury Thiocyanate Spectrophotometric Determination of Chlorine in Ores

摘要: 岩石样品经氧化锌-碳酸钠烧结预处理,用水浸取后澄清,取清液用硫氰酸汞间接分光光度法进行氯的测定.方法用于实际样品的分析,结果与其他方法测定值一致,误差均在允许范围内;对氯含量为1.08%(质量分数)的样品重复测定6次,精密度(RSD)为1.74%.方法适用于0.02%-2%氯的测定,并且方法简单、快捷、准确,避免了用高氯酸调节酸度的繁琐操作.

Abstract: A method for the mercury thiocyanate spectrophotometric determination of chlorine in ore samples was reported in this paper. The sample was sintered with zinc oxidesodium carbonate and then leached with water. Chlorine in the sample solution was indirectly determined by mercury thiocyanate spectrophotometry. The results are in good agreement with those from other methods with precision of 1.74%RSD (n=6) for the sample with 1.08% chlorine. The method is suitable for the determination of chlorine in the samples with 0.02%～2% of chlorine with the advantage of simplity, rapidity, accuracy and less tedious procedure.
