Abstract
An on-line neutralization of matrix-ion chromatography for determination of chloride ions in lithium was established and the selection of different column temperatures and sample sizes was studied.The relative standard deviation of chloride ions was less than 3%,the spiked recovery rate was 94%-105%,and the measured content was 5.4 μg/g.The method is simple,rapid,highly accurate and sensitive,and suitable for analysis of chloride ions in lithium,to improve the detection level and analysis efficiency.
