| 摘 要： | 开展椰壳活性炭对活性染料K-2BP、KN-B和KN-R的吸附脱色研究。发现K-2BP、KN-B和KN-R在该型活性炭上的吸附脱色率均随初始pH值的降低、温度的升高、染料初始浓度的降低、活性炭用量的增加以及NaCl盐度的增加而增加。在pH=7和T=25℃下,K-2BP、KN-B和KN-R在活性炭上的等温吸附规律符合Langmuir模型方程,最大饱和吸附量Qmax分别为263.15、256.41和250 mg/g,吸附自由能△G298 K分别为-10.632、-3.783和-2.805 kJ/mol;该条件下K-2BP、KN-B和KN-R的动力学吸附规律均符合准一级动力学吸附方程。等温吸附研究和吸附动力学研究均表明,相同条件下3种活性染料在该型活性炭上的吸附效果由高到低的顺序为:K-2BP>KN-B>KN-R。
