| Abstract: | We develop the method to determine the content of Chloride in tap water samples.Under optimized experimental conditions,the chloride concentration has good linear relationship with absorption in the range of 1 ～ 200mg/L.The regression equation was Conc.=-3 679.657Abs2 ＋ 2 448.946Abs -17.154,r =0.998 8.The recovery this method can reach about 98.98％ ～ 101.64％.The method has the advantages,such as briefness,rapidity,less interference,good accuracy and precision,which is suitable for use in the field of environmental monitoring. |
