摘　　要：湿法炼锌在中性浸出后需加入大量锌粉除杂,在这个过程中可能因锌粉质量问题而引入对锌电积影响严重的锡元素,故对进入生产系统的锌粉需分析其中锡含量是否达到生产要求,进而从源头上杜绝有害锡元素进入生产系统。本实验采用氢化物发生-原子荧光光谱法测定锌粉中锡含量,实验结果表明该方法精密度和准确度良好,能满足生产厂对锌粉中锡含量检测的需求。Wet zinc smelting requires the addition of a large amount of zinc powder for impurity removal after neutral leaching.During this process,tin elements,which have a serious impact on zinc electrodeposition,may be introduced due to quality issues with zinc powder.Therefore,it is necessary to analyze whether the tin content in the zinc powder entering the production system meets the production requirements,in order to prevent harmful tin elements from entering the production system from the source.This experiment uses hydride generation atomic fluorescence spectrometry to determine the tin content in zinc powder.The experimental results show that this method has good precision and accuracy,and can meet the needs of production plants for detecting tin content in zinc powder.
