A study of adsorption of indium with N-503 levextrel resin

The adsorptivity of N-503[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 N-503 levextrel resin to indium in HBr medium were also discussed, The results show that the adsorption of the N-503 levextrel resin to indium is carried our 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 N-503 levextrel resin to indium abides by the following equation: In3++H++4Br(-)+2<(N-503)over bar>=<(N(5032)HlnBr(4))over bar>
