摘要
建立了以AS19阴离子交换分离柱,KOH淋洗液自动发生器,抑制型电导检测器测定水中碘离子的离子色谱方法,优化了色谱条件,结果表明方法不受F-、Cl-、NO2-、NO3-、PO42+、SO42-干扰,检出限为0.001 mg.L-1,线性范围在0.001 mg.L-1～1.000 mg.L-1,相关系数R2=1,精密度高,准确度好。
The establishment of an AS19 anion exchange column, K0H eluent generator, and suppressed conductivity detector for the determination of iodine in water by ion chromato-graphic method, optimization of chromatographic conditions. The results show that the method is not subject to F-,Cl-,NO2-,NO3-, PO43-,SO42- interference, The detection limit is 0.001mg. L-1 ,the Linear range from 0.001mg. L-1 to 1.000 mg · L-1 and the ecorrelation coefficient R2=1. The precision and accuracy was excellent.
