【Abstract】 The determination of fluoride in water with ion selective electrode method was studied and discussed in this paper.The thoroughgoing analysis of the constitution of ion selective electrode and the principle of determination were made.The electrode blank and electrode solpe and determination temperature and standard curve that were happened in determination were discussed deeply.It is happened to contrast determination of fluoride and IC.The experiment results showed that the accuracy and repeatability of the method was satisfied.The conclusion was come to that there was no obvious difference between the methods to IC.This method is more selective and accurate and rapid than others,it can be applied to measure fluoride which concentration is between 0.05～1900mg/L in water,especially to large number of daily samples.更多还原
