Abstract: | Sulfate in silicon hydrofluoric acid was determined by ion chromatography. The sample was treated with hydrochloric acid,to exclude the fluride in silicon hydrofluoric acid by volatilization,the detremination was done by using 883 Basic IC Plus ion chromatograph. The linear range is of 0 ~ 20 μg / m L,the detection limit is of 0. 098 μg / m L,correlation coefficient is of 0. 999,recoveries are between 98% and103%. The results show that this method is simple,rapid and accurate,to meet production needs. |
