| Abstract: | An fluoride ion-selective electrode(ISE) assay was developed for the determination of fluoride in the vegetables,which were digested firstly in HNO3 solution and detected directly in the total ionic strength adjusting mixture(TISAM) solution.The linear range for the determination of fluoride was between 1.00 ×10-6-1.00 ×10-2 mol/L,and the detection limit of the method was 13.5 μg/L.This method was used for the determination of trace fluoride in the vegetables with satisfied results. |
