摘　　要：The absorption of free alkali at low concentration by subacid resin was traced with electric conductance method, the effect of temperature on the adsorption, the activation energy of adsorption (Ea) and interaction energy (U) was studied. The result showed that, the process of low concentration alkali adsorption by subacid resin was in accordance with mechanism of monomolecular layer absorption, in addition, with the increasing of temperature, the interaction energy between adsorbate and sorbent increase, so did the surface adsorption rate (k), and linear correlation existed between interaction energy (U) and temperature (T).The absorption of free alkali at low concentration by subacid resin was traced with electric conductance method, the effect of temperature on the adsorption, the activation energy of adsorption (Ea) and interaction energy (U) was studied.
