摘　　要：将氧化钼样品经处理转化为钼酸铅沉淀后,以微波炉代替马弗炉对沉淀进行了干燥试验,同时对氧化钼的水分测定也采用了微波干燥法。结果表明,利用微波法可使沉淀干燥的时间由30 m in缩短为7 m in,氧化钼干燥时间由2 h缩短为4 m in。显著提高了样品中钼和水分的测定速度。After the sample of molybdenum oxide was changed into lead molybdate sedment, the sedment was dried by microwave, and at the same time the moisture in molybdenum oxide was also determined by microwave. The resuits showed that the drying time of the sedment was shortened from 30min to 7min and that of molybdenum oxide from 2h to 4min by microwave.

关 键 词：微波干燥 氧化钼 钼酸铅沉淀 水分
