PTSO is abbreviated from di-P-tolyl Eolphoxide having a>S=0 group and is a neutral extractant.We have studied the behaviour and conditions of the separation of Au(Ⅲ) from other elements on a column packed with the silica gel loaded with PTSO and have found that PTSO is a new stationary phase with extremely high selectivity for the separation and concentration of gold.However,the application of PTSO to the solvent extraction has not bean reported yet.We first studied the behaviour and mechanism using PTSO to extract gold by atomic-absorption spectrophotometry,ultra-violet spectrophotometry and infra-red spectrophotometry.The possible structure of the extractive formed from PTSO and Au(Ⅲ) is suggested.

We have studied the behavior and conditions of the separation of Au (III) from other elements on a column packed with the silica gel loaded with PTSO and have found that PTSO is a new stationary phase with extremely high selectivity for the separation and concentration of gold. Host, the application of PTSO to the solvent extraction has not bean reported yet .We first studied the behavior and mechanism using PTSO to extract gold by atomic absorption spectrophotometry, ultra-violet spectrophotometry and infra-red spectrophotometry.
