摘要
提出用无水碳酸钠预处理试样,用硫氰酸汞进行比色测定聚乙烯中微量氯的方法。该方法最小检出质量浓度约1 0×10-5g/ml,相对标准偏差小于5%,实际试样测定结果的相对误差小于5%。
Mercuric rhodanide colorimetric determination of trace chlorine in polyethylene was investigated.The sample was pretreated with anhydrous sodium carbonate before determination.Minimum detectable concentration was about 1.0×10^(-5) g/ml.RSD of analytical results in polyethylene samples was less than 5.0%,and relative error was less than 5.0%.
