催化裂化废催化剂吸附废水中镍离子的研究

Study on The Adsoption of Ni^(2+)onto FCC Wastcatalyst

研究了催化裂化废催化剂对镍离子的吸附性能，考察了振荡时间。温度和pH值等对吸附效果的影响。研究结果表明，振荡时间、温度及pH值对吸附效果均有较大影响。吸附规律可用Freundlich和angmuir模式较好模拟，吸附呈单分子层吸附形式，且吸附容易进行。

The effects of adsorption tine, temperature and pH value on the adsorption efficiency was inspected in this paper. The results show that adsorption time, temperatule and pHvalue are the main factors to affect adsorption efficiency. The adsorption of Ni2+ onto FCC waste catalyst is classified to mono - molecular type, which can be well described by Freundlich and Langmuir model.Ni2+ is easy to be adsorbed.
