| Abstract: | In this paper, the alkalinity borax solution of pH 10 was selected for medium of determination. To eliminate the oxygen in the medium by Vitamin C, the method of determination of trace sulphur with visigiph polargraphy was studied by the test, and mechanism of method was preliminarily explored. There is good linearity that the concentration of sulphur was between 1.0×10-5～1.0×10-7 mol/L. Limit of detection was 5.0×10-8 mol/L. The relative standard deviation of method was 0.49%. The disturbance of usual metal ion can be eliminated with the suitable shelter. The results might get satisfied that method was applied to determin various water specimens. |
