In this paper, ion chromatography and ion selective electrode method were used to determine fluoride in surface water. Both methods achieved better accuracy、precision and recovery rate. The experimental results show that the relative error of the ion chromatography and the ion selective electrode method for the sample determination is less than 2. 0 ％, the relative standard deviation for the actual sample determination is less than 1. 0 ％, and the standard recovery rate meets the requirements of 90 ％-110％. There is no significant difference in the determination results of the two methods. If the surface water is a relatively clean water sample, ion chromatography method directly filters the sample, which is easier and faster.
