钼铁中钼的测定方法已有重量法、容量法、光度法,均难兼顾准确、快速、稳定等特点。铜盐催化,硫氰酸盐为显色剂差示光度法测定矿石中钼已有报导,为了进一步提高显色速度和稳定性等,本文又对高量钼的硫氰酸盐显色过程进行了探讨,从而揭示了其过程中的部分特性,并试验了钼铁中钼的双向差示光度分析法,其简便。快速、易掌握、测定范围广、稳定性好、准确度和
Molybdenum molybdenum in the determination of the weight method, volumetric method, photometry, are difficult to take into account the accuracy, speed, stability and so on. Copper salt catalysis and thiocyanate as chromogenic agent differential spectrophotometry for the determination of molybdenum in ore have been reported. In order to further improve the color developing speed and stability, this paper also studied the chromogenic thiocyanate chromogenic process In order to reveal some characteristics of the process, the two-way differential spectrophotometry of molybdenum in ferromolybdenum was tested, which is simple and convenient. Fast, easy to grasp, measurement range, stability, accuracy and
