农田灌溉水中阴离子的色谱分析
Chromatographic Analysis of Anions in Agricultural Irrigation Water
摘要
Abstract
For efficient and rapid detection of anions in irrigation water,a method for the determination of four anions, namely F-,Cl-,NO-3、SO2-4, by ion chromatography(IC)with the solid phase extraction(SPE)was established. Influences of eluent concentration and flow rate on ion retention time and resolution were discussed. Meanwhile,the chromatographic conditions were optimized as follows.The eluent is 4.5,mmol/L Na2,CO3/0.8,mmol/L NaHCO3,and the flow rate is 1,mL/min. The four anions’ detection limit is 0.002~0.048,mg/L,the precision is lower than 2%,and the recovery ranges from 93.79%to 104.30%. The method is simple,reliable and suitable for the simultaneous determination of several anions in agricultural irrigation water.关键词
