摘要
制备出氯代十六烷基吡啶(CPC)改性磁性硅藻土,通过FTIR进行表征,并将其用于废水中染料甲基橙的去除.本文主要考察了时间、pH、温度等条件对CPC-磁性硅藻土吸附性能的影响.该吸附过程符合准二级吸附动力学模型,等温吸附模型表明该吸附均符合Langmuir模型.
The cetylpyridinium-chloride-modified magnetic diatomite were prepared and characterized by FTIR.It is used for the removal of dye methyl orange in waste water.The influence of time,pH,temperature,and other conditions on the adsorption properties of CPC-magnetic diatomite is studied. The kinetics model of adsorption corresponds to pseudo-second-order kinetics. The isothermal adsorption model showed that the adsorption was in accordance with the Langmuir model.
