摘    要：研究了N503(N,，N-二仲辛基乙酰胺)萃淋树脂在HCl体系中对镓的吸附性能。测定了树脂对镓的吸附速率和吸附等温线，发现树脂吸附镓按假一级反应进行，并符合Freundlich吸附等温式。根据吸附平衡和红外光谱的研究发现，N503萃淋树脂吸附稼的反应按下式进行：

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:
