Abstract: The adsorptivity of N503 (N , N-di (sec-octyl) acetamide) levextrel resin to gallium in the HCl medium was studied. The adsorption rate and adsorption isotherm of the resin to gallium were measured. The results show that the adsorption of the resin to gallium is carried out in pseu-do first order reaction and follows Freundlich isothermal adsorption equation. The adsorption equilibrium and infrared spectrum study show that the adsorption reaction of N503 levextrel resin to gallium obeys the following equation :
2N503+H++Ga3++4Cl-=(N503)2H4GaCI4
2N503+H++Ga3++4Cl-=(N503)2H4GaCI4
Key words: gallium adsorption N503 levextrel resin
