摘要：

A simple selective and sensitive method for the determination of selenium has been investigated. Sodium isopropyl xanthate was used as a reagent and chloroform as an extractant. The complex was extracted into chloroform from pH 4 acetate buffer. The influence of various interferences ions on the extraction was studied. 3-10 mu g selenium was determinted with a precision of 1.42%. The method developed was utilized to determine the selenium content in Jaggery and wheat samples.
