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 re-suits show that the adsorption of the resin to gallium is carried out in pseudo first order reaction and follows Fre-undlich isothermal adsorption equation. The adsorption equilibrium and infrared spectrum study show that the ad-sorption reaction of N503 levextrel resin to gallium obeys the following equation:
