摘要
建立了使用电感耦合等离子体质谱仪测定锌湿法冶炼电解液中铊含量的方法,样品经过稀释在稀硝酸介质中,205Tl为测量同位素,以He作为碰撞气体,185Re作内标校正干扰,用工作曲线法计算铊的含量.该方法测定锌电解液中铊含量的检出限为0.2ng/L,相对标准偏差小于5%,方法试验回收率在96%～101.1%之间,具有良好的准确度和精密度.
Abstract
A method for the determinationof Thallium content in zinc hydrometallurgy electrolyte by inductively coupled plasma mass spectrometry was established through experiments.The sample was diluted in dilute nitric acid medium,205Tl was used as the measuring isotope,He was used as collision gas and 185Re was used as internal standard to correct interference,and the thallium content was calculated by standard curve method.The detection limit of thallium content in zinc electrolyte is 0.2ng/L,the relative standard deviation is less than 5%,and the recovery rate of the method test is between 96%and 101.1%,which has good accuracy and precision.
