摘要: 考察了N503萃淋树脂在盐酸、氢溴酸、硫酸-溴化钠体系中对铟的吸萃性能,研究了N503萃淋树脂在氢溴酸体系中吸萃铟的动力学和机理,发现N503萃淋树脂吸萃铟的反应按假一级反应进行,并符合Freundlich等温吸附式。吸附平衡和红外光谱研究发现N503萃淋树脂吸附铟的反应按下式进行:In3++H++4Br-+2N503 =(N503)2HInBr4

关键词: 铟, N503萃淋树脂, 吸萃机理

Abstract: The adsorptivity of N503 [N,N-di (sec-octyl)acetamide] levextrel resin to indium in HCl,HBr and H2SO4-NaBr media was studied.The adsorption kinetics and adsorption mechanism for N503 levextrel resin to indium in HBr medium were also discussed.The results show that the adsorption of the N503 levextrel resin to indium is carried out in pseudo first order reaction and follows freundlich isothermal adsorption equation.Studies on the adsorption equilium and infrared spectrum show that the adsorption reaction of N503 levextrel resin to indium abides by the following equation: In3++H++4Br-+2N503=(N503)2HInBr4

Key words: Indium, N503 levextrel resin, Adsorption mechanism
