钼的催化极谱测定国内外已有不少报导,但是,通常大量钨对钼的测定都有严重影响。目前,钨精矿中少量钼的直接极谱测定仍有困难。本文研究了钼在EDTA-(NH_4)_2SO_4-KClO_3支持电解质中的催化波,大量钨没有影响,解决了钨精矿中少量钼的测定问题。本法已用于钨精矿及其选矿尾矿等中0.00X—4％钼的直接测定。分析
Catalytic polarographic determination of molybdenum has been reported at home and abroad, however, a large number of tungsten usually have a serious impact on the determination of molybdenum. At present, the direct determination of molybdenum in tungsten concentrates by direct polarography is still difficult. In this paper, the catalytic wave of molybdenum in EDTA- (NH_4) _2SO_4-KClO_3 supporting electrolyte has been investigated. A large amount of tungsten has no influence on the determination of a small amount of molybdenum in tungsten concentrates. This method has been used for the direct determination of 0.00X-4% molybdenum in tungsten concentrates and their dressing tailings. analysis
