矿石中高含量钨和钼的测定通常采用重量法和差示分光光度法分别测定。本法采用碳酸钠-氧化锌烧结分离大部份干扰元素后,选择在酒石酸-磷酸-抗坏血酸底液中测定钼。在测完钼后的试液中加一定量的盐酸和动物胶再测定钨。在同一份试液中完成了钨和钼的测定。方法快速,准确,重现性好。测定矿石中高含量的钨和钼获得了良好的结果。
Ore determination of high levels of tungsten and molybdenum are usually gravimetric and differential spectrophotometric determination. This method uses sodium carbonate - zinc oxide sintering separation of most of the interference element, the choice of tartaric acid - phosphoric acid - ascorbic acid in the determination of molybdenum. Tested in molybdenum after the test solution plus a certain amount of hydrochloric acid and animal glue and then measure the tungsten. In the same test solution to complete the determination of tungsten and molybdenum. The method is fast, accurate and reproducible. Good results have been obtained in the determination of high levels of tungsten and molybdenum in the ore.
