氧化镁烧结-电感耦合等离子质谱法测定冰铜中的铼

本文建立了一种利用电感耦合等离子体质谱法（ICP-MS）测定冰铜中铼的方法。样品经氧化镁烧结，热水浸取法处理，溶液经732强酸型阳离子交换树脂处理交换去除干扰离子，实现了ICP-MS直接测定冰铜中的铼。实验结果表明，在最佳试验条件下，方法的检出限可低至0.010mg/t，加标回收率为92.00%~104.00%，测定结果的相对标准偏差（RSD，n=7）小于5%，测定结果令人满意。由此可见，该方法精密度高，准确度高，可用于冰铜中铼的测定。

Determination of Rhenium in matte by Inductively coupled plasma-mass spectrometry with magnesium mxide sintering

A method for the determination of rhenium in matte by inductively coupled plasma mass spectrometry (ICP-MS) was established. The sample was sintered by magnesia and soaked in hot water, and the solution was treated by 732-type cation exchange resin to remove the interference ions, which could direct determinate the rhenium in matte by ICP-MS. The experimental results show that under the optimum test conditions, the detection limit of the method can be as low as 0.010mg/t, and the recovery rate is 92.00%-104.00%. Meanwhile, the relative standard deviation (RSD,n=7) of the determination results is less than 5%. which are satisfactory. Thus it can be seen that the method has high precision and accuracy and can be used for the determination of rhenium in matte.
