在 YCl_3—HCl—H_2O—D2EHPA(在美国矿物精公司的无嗅矿物溶剂中)系统中测定分配系数 E,最终钇的水溶液浓度 X=0.0001～2.6克分子/升,最终酸度 H=0.4～12克分子/升和开始 D2EHPA,浓度 C_1=0.3～2克分子/升,以 E=K′XmHn C_1p 形式表示。发现 peppard 的简单的离子交换萃取反应,仅在低的 X 时及在一定的 H 范围内,才是生效的。在1M 溶液中 Y=0.145时,在有机相中,能看到了白色沉淀的聚合物 YG_3,G=〔C_4HaCH(C_2H_5)CH_2〕Po_4~-,在预先计算的时候,Y=0.166。E 随着 H~+浓度的变化是十分惊人的。
The partition coefficient E was determined in a YCl 3 -HCl-H 2 O-D2EHPA system (in U.S. Mineral Essence’s non-odorless mineral solvent) system and the final concentration of yttrium in aqueous solution was X = 0.0001-2.6 mol / L and final acidity H = 0.4-12 D2EHPA at a concentration of C_1 = 0.3-2 mol / l, expressed as E = K’XmHn C_1p. The peppard’s simple ion exchange extraction reaction was found to be effective only at low X and within a certain H range. When Y = 0.145 in 1M solution, white precipitated polymer YG_3 was observed in the organic phase, G = [C_4HaCH (C_2H_5) CH_2] Po_4 ~, and Y = 0.166 at pre-calculated time. E With H ~ + concentration changes is very alarming.
