摘要
对磷矿石中P2O5、Al2O3,caO、MgO、Fe2O3、Cd测定方法进行研究,确定试验最佳条件。元素回收率95.3%~105.4%,相对标准偏差(n=12)为2.53%-5.80%,检出限为0.5×10^-6-7.86×10^-6。经几种国家标准物质及矿石样品分析验证,结果满意。
The best testing conditions are determined according to the study on the testing method of P2O5, Al2O3, CaO, MgO, Fe2O3, Cd in P ore. The element recovery 95.3%- 105.4%, relative standard deviation (n = 12) 2. 53% -5.80%, limit of detection 0. 5ppm -7. 86ppm. The results are satisfactory according to the analysis examination of several state standard materials and ore samples.
