国家标准钼精矿中钼的测定方法探讨

Study on the Determination Method of Molybdenum Quantity in National Standards Molybdenum Ore Concentrate

对国家标准GB/T 15079.1-1994钼精矿化学分析方法钼的测定,确定了干扰元素钨、钒、铬等的消除方法;并将不溶残渣的处理由混合溶剂烧结改为氢氧化钠熔融,从而提高了方法准确度,扩大了使用范围。

The determination of molybdenum in national standards GB/T 15079. 1- 1994 molybdenum concentrates shows the inteferences of element tungsten, the vanadium, the chromium and so on, as well as the insoluble residue from the handling of mixed solvents sintering sodium hydroxide to melt, The study established an elimination method for the interferential elements and insoluble residue to enhance the accuracy of the method, expanding the scope of use.
