摘　　要：对钒钼矿中的钼的测定进行了探讨。采用苯羟乙酸-氯酸钾-EDTA-酒石酸体系，加入抗坏血酸-ED-TA消除钒及锡的影响，用催化极谱法测定钼的含量。试验了浸出条件、酸度及主要试剂对本方法的影响。方法简单，灵敏度高。测定范围：0．0005％-5％。The determination of molybdenum in vanadium molybdenum ore is discussed. The mandelic acid-potassium chlorate -ElYrA-tartaric acid system is adopted, and the ascorbic acid-EDTA is added to remove the effects of vanadium and tin. The molybdenum content is determined by catalytic polarographic method. The effect of leaching conditions, acidity value and main reagents on this method are tested. This method is simple and with high sensitivity. The determination range is 0. 0005% -5%.
