本文简要介绍了国内外有关石油亚砜研制和应用概况,并应用光度法测定了4种溶剂中硫氰酸钼(Ⅴ)配合物的组成、累积稳定常数和相应的摩尔吸光系数.然后用石油亚砜为萃取剂,分别以三氯甲烷和四氯化碳为它的稀释剂,对上述体系中硫氰酸钼(Ⅴ)配合物进行了萃取光度研究.计算了在各有机相和水相中对硫氰酸钼(Ⅴ)的分配比与水相中硫氰酸根浓度的函数关系并讨论了有关的萃取机理.
This article briefly introduced the domestic and international research and application of petroleum sulfoxide, and determined the composition, cumulative stability constant and corresponding molar extinction coefficient of molybdenum (Ⅴ) thiocyanate in four solvents by spectrophotometry. Sulfoxide as extractant, respectively, with chloroform and carbon tetrachloride as its diluent, the above system of molybdenum thiocyanate (Ⅴ) complexes were extracted photometric studies were calculated in each organic phase and aqueous phase The relationship between the distribution ratio of molybdenum (Ⅴ) thiocyanate and the concentration of thiocyanate in aqueous phase was discussed and the related extraction mechanism was discussed.
