实验在具有悬浮的锐钛矿型二氧化钛颗粒的反应器中进行。吸附量随着pH值从pH 2到5的增加而迅速增加，并且在pH 5以上保持恒定。在15 ℃ ~ 40 ℃范围内，吸附量随温度的升高而增加。吸附平衡常数（K-ads）为0.854，吸附等温线符合Langmuir吸附等温线，而Freundlich吸附等温线则不符合Langmuir吸附等温线。随着254 nm紫外灯数量的增加，吸附速率迅速。(C)2003年由Elsevier Science Ltd.出版
The experiment was performed in the reactor with suspended anatase-type titanium dioxide particles. The adsorption amount increased rapidly with an increasing pH value from pH 2 to 5 and remained constant over pH 5. The adsorption amount of Cu2+ increased with temperature from 15degreesC to 40degreesC. The adsorption equilibrium constant (K-ads) was 0.854 and adsorption isotherm of Cu2+ adsorption on titanium dioxide was more suitable in Langmuir adsorption isotherm than in Freundlich isotherm. The adsorption rate was rapid with an increasing number of UV lamps of 254 nm. (C) 2003 Published by Elsevier Science Ltd.
