内容記述 | Sodium benzoate reacts with uranyl ion in the presence of zephiramine (tetradecyl-demethyl-benzyl-ammonium chloride; Zeph+. C1-) to form ion association complex of whitish-yellow precipitate. The complex is extracted into chloroform and determined by the polarographic method in O. 5 M H_2 SO_4 as supporting electrolyte. 97.2 % of uranyltribenzoate-zephiramine complex is extracted at pH 4.0-6.0. Under the optimum condition, diffusion current at - 0.58 V (vs. S. C. E.) is proportional to uranyl ion concentration in the range of 10-^<-4>-10^<-3> M. The composition of the extracted species is assumed to be (Zeph+. UO_2 (C_6H_5COO)_3(H_2O)_3-) and more than 95.2 % of the complex compound is stripped by 0.5 M H_2 SO_4. | |||||||||
