光谱法测定选矿产品中低含量氧化钇

DETERMINATION OF A SMALL AMOUNT OF Y_2O_3 IN A MINERAL PROCESSING PRODUCT BY A SPETROGRAPHIC METHOD

本文建立了一个光谱法测定选矿产品中氧化钇的方法。方法简便、准确。已成功地应用于选矿试验分析，测量范围为０．００１５％～０．３％，标准加入回收宰为９５％～１０５％，测量相对均方差为１０％。

In this paper the determination of Y_2O_3 in a mineral processing product by AESis studied. The method developed has the advantages of simplicity and rapidity in operation,and high accuracy. The calibration curve is linear in the range of 0. 0015%～0.3%. Recov-ery is found to be 95%～105%, and relative standard deviation 10%。 This shows that theresults are satisfactory.
