丙硫醚中无机杂质含量分析研究

Analysis of inorganic impurities in propylene sulfide

采用ICP-MS法分析确定了丙硫醚样品中K^(+)、Na^(+)、Mg^(2+)、Fe^(2+)浓度,采用离子色谱法分析确定了丙硫醚样品中溴离子与硫酸根离子的浓度,通过外标法确定了丙硫醚中的无机杂质含量为0.0074%。

The concentration of the K^(+),Na^(+),Mg^(2+) and Fe^(2+) in the sample of propylene sulfide was determined by ICP-MS,and the concentration of bromine ion and sulfate ion in the sample of propylene sulfide was determined by ion chromatography,the content of inorganic impurities in propylene sulfide was 0.0074% by external standard method.
