Dithizonates and diethyldithiocarbamates of Ag, Tl(I), Cu(II), Zn, Cd, Hg(II), Pb, Fe(II), Co(II), Ni, Pd(II), In(III), As(III), Sb(III), Bi, Se(IV) and Te(IV) have been prepared and their reactions in carbon tetrachloride have been studied spectrophotometrically. From the exchange constants determined, the extraction constants of metal diethyldithiocarbamates have been calculated. Where formation
Ag,Tl(I),Cu(II),Zn,Cd,Hg(II),Pb,Fe(II),Co(II),Ni,Pd(II),In(III),As的双硫iz酸盐和二乙基二硫代氨基甲酸盐制备了(III),Sb(III),Bi,Se(IV)和Te(IV),并用分光光度法研究了它们在四氯化碳中的反应。从确定的交换常数,已经计算出二乙基二硫代氨基甲酸金属盐的萃取常数。在观察到混合螯合物形成的情况下,已经确定了相应的交换常数。最后,研究了有机溶剂(CCl(4),CHCl(3),C(6)H(6)和C(6)H(5)Cl)对二乙基二硫代氨基甲酸锌与双硫zone交换反应的影响。
