摘　　要：通过静态吸附试验,研究了H-103大孔树脂对水溶液中对苯二酚的吸附动力学及热力学特性,结果表明吸附符合一级动力吸附方程,颗粒内扩散过程是影响吸附速率的主要控制步骤。吸附符合Freundlich等温吸附方程,吸附为放热的物理吸附过程。适当的降低温度有利于吸附。The thermodynamic properties and kinetics of adsorption of aqueous solution of hydroquinone on H-103 macroporous resin were studied by the static adsorption experiment. The results show that the ad- sorption rate for the solute appears to follow the first order kinetics, and the irtra particle diffusion is the main rate controlling step. The adsorption data fit well into the Freundlich adsorption isotherm, and the adsorption is an exothermic physical adsorption process. To reduce the temperature properly is in favor of the adsorption.
