分光光度法测定丙烯中的痕量硫

Determination of Trace Sulphur in Propylene by Spectrophotometry

建立了分光光度法测定丙烯中痕量硫的方法,当样品中硫质量分数在0—1mg/kg内,样品中硫含量与吸光度呈良好的线性关系,检出限为0.1mg/kg。该方法适用于丙烯中痕量硫的测定。

A method of determining trace sulphur in propylene by spectrophotometry was developed.The sulphur content is linear with absorbance when the mass fraction of sulphur is in the range of 0—1mg/kg,the detection limit is 0.1mg/kg.The method is suitable for determining trace sulphur in propylene.
