| 摘 要： | 研究了活性炭自水溶液吸附苯酚的吸附规律和机理，对不同吸附温度和溶液pH值下吸附常数和热力学函数进行了估算，结果表明：活性炭自水溶液吸附苯酚符合Langmuir模型；低温度低pH值下苯酚被吸附的量大，熵增效应小，而高温度高pH值下苯酚被吸附的量小，熵增效应大，整个吸附过程中熵增效应随吸附量的增加而减少。

| Abstract: | Having studied the characteristics and mechanism of phenol adsorption from aqueous solution with activated carbon and estimated adsorption constants and thermodynamic parameters in the different temperature and pH, we have obtain the results that the method of adsorbing phenol form aqueous solution to the l angmuir model. The adsorptive capacity is high and the entropy effect is lower i n the lower temperature and pH. On the contrary, the adsorptive capacity is lowe r and the entropy effect is high in the high temperature and pH. In the adsorpti on the entropy effect was decreases with the increasing of the adsorptive capac ity. |
