摘　　要：本文用分光光度法研究了在不同浓度的丙酮 -水溶液中硫氰酸钼 ( )络合物 ,以石油亚砜 (PSO) -三氯甲烷 (CHCl3 )萃取剂的萃取行为。由分光光度数据直接计算萃取分配比 ,讨论了分配比与混合溶液中硫氰酸根浓度的函数关系 ,研究了丙酮在混合溶液中体积百分数的增加对分配比和萃取百分率的影响 ,并对实验结果进行了解释 ,实验表明 ,Mo O(SCN) 3The extraction behaviour of molybdenum (Ⅴ) thiocyanate complex in the different concentration solution of acetone with water used petroleum sulfoxide\|chloroform as extractant was studied by spectrophotometry.The distribution ratio of extraction was directly calculated by using the data of spectrophotometry.The function relation on the distribution ratio with the concentration of thiocyanate in mixed solution was discussed.The effect of percent increment by volume of acetone in mixed solution on distribution ratio and percentage of extraction was studied,respectively.And the experimental results was explained.It shows that the extraction system of MoO(SCN) 3 has value in application.
