摘要
快速准确测定铜铅锌矿石中的铼对于铼的提取回收有着重要意义。本文建立用MgO烧结分解-水提取,电感耦合等离子体质谱(ICP-MS)法测定铜铅锌矿石中铼的方法。该方法优化了前处理步骤,在保证准确度的前提下,简化了操作流程,提高了工作效率,方法检出限、精密度、准确度、加标回收率均满足实验要求,可用于实际生产中。
A fast and accurate determination method of rhenium in copper-lead-zinc ore is of great significance for the extraction and recovery of rhenium.In this paper,a new method was proposed to determine Re in copper-lead-zinc ore by combining the MgO sintering decomposition-water extraction and ICP-MS.The new method can simplify pre-processing steps,and has good detection limit,precision,accuracy and recovery of standard addition,so the method can meet the requirements of practical application.
