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萃淋树脂吸附镓的反应按下式进行：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 pseudo 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:
