Gongye shui chuli, 2015 用KOH对市售的粉末活性炭进行表面改性。采用BET分析改性前后活性炭的表面结构,并采用活性炭涂层电极构建电容去离子吸附装置,研究改性后电极的去离子效果。研究表明:经过KOH改性后,活性炭的比表面积从519.25 m2/g增加到975.07 m2/g,提高了87.78%,中孔孔容占总孔孔容的百分比提高了48.28%,改性后活性炭的孔隙结构和孔径的分布更有利于溶液中的Na+和Cl-通过,提高了电极的吸附速率。

Gongye shui chuli, 2013 研究了活性炭对亚甲基蓝、甲基橙、中性红的吸附特性。结果表明,活性炭吸附3种典型染料的qt～t、qe～pH、qe～T曲线趋势基本上是一致的,活性炭对亚甲基蓝染料的吸附能力最强。另外,活性炭对3种染料的吸附行为均符合Langmuir等温吸附和准二级动力学方程,其中,内扩散过程是活性炭吸附亚甲基蓝的速率控制步骤,但不是吸附甲基橙和中性红的速率控制步骤。
