摘要(Abstract):
研究了吸附柱高度对锰氧化物/沸石(MOCZ)吸附中性红(NR)的动态影响.结果表明,MOCZ吸附NR的平衡吸附量随着柱高的增加而增加.对不同柱高条件下的实验结果分别用Thomas,Yoon-Nelson和Adams-Bohart动态吸附模型进行线性和非线性拟合,结果说明穿透曲线初始阶段很好地符合Adams-Bohart动态吸附模型,Thom-as和Yoon-Nelson模型的预测点和实验点的变化趋势相同.误差分析说明线性和非线性方法均可用于预测流出曲线,且非线性方法的误差较小,优于线性分析.最后用BDST模型对实验数据进行了分析.
关键词(KeyWords): 锰氧化物/沸石(MOCZ);中性红;柱吸附;动态模型
