摘要

The water-soluble fluoride in soil samples was determined by ion-selective electrode method, and good results were obtained. The detection limit was 0.314 mg/kg and the lower limit was 1.26 mg/kg. The relative standard deviation (n=7) between 3.82% and 6.28%, and the relative error (n=7) between 1.6% and 5.8% were obtained by the precision and accuracy analysis of standard materials (GBW07412a, GBW07414a, GBW07459). The test results show that the relative standard deviation and relative error of the test sample are within the allowable range.
