摘要
本文探讨了采用ICP-MS法测定戴家河金矿样品中的金含量,通过优化仪器参数消除了质谱干扰,选用~(185)Re作为内标元素,进行了基体校正,并结合矿区含金样品的实际含量范围,省去泡塑吸附步骤,对样品前处理进行简化,节省了前处理时间。通过实验证明:本方法具有较高的准确度,方法的检出限、精密度等均能满足该矿区样品中金的测定要求。由此可见,将该方法应用于金矿勘查中金的测定,具有良好的推广价值。
This paper discussed the use of ICP-MS to determine the gold content in samples from the Daijiahe gold deposit.By optimizing the instrument parameters to eliminate the interference of mass spectrum,185Re was selected as the internal standard element for matrix correction,and in consideration of the actual range of go content in the samples from the mineral district,foam adsorption was omitted,sample pretreatment was simplified,and the pretreatment time was saved.The experimental results show that the method has high accuracy,and its detection limit and precision can meet the requirements for determination of gold in the samples from the district.It can be concluded that the application of this method to the determination of gold in the process of gold exploration can be popularized.
