摘要
Abstract
Based on ion chromatography,this paper establishes a new method for rapid determination of iodide ions in water samples from the Yellow River Basin.The results show that the linear range is 0.10 to 5.00 mg/L,with a correlation coefficient r greater than 0.9998.The detection limit of the method reaches 0.005 mg/L,and the recovery rate of spiked samples ranges from 97.2%to 102.1%.In the recovery experiment using standard samples,when measured six times repeatedly,the RSDs of the original sample and the spiked sample are 0.55%and 0.30%,respectively.This method can quickly and effectively determine the concentration of iodide ions in environmental water,with the advantages of good precision and high sensitivity.It can be applied to industrial production and scientific research.关键词
