| 摘 要： | 以废弃物木屑和花生壳作为吸附剂,进行了吸附去除水中Cr3 的试验.研究了溶液pH值、初始Cr3 浓度以及温度等因素对这2种吸附剂去除Cr3 作用的影响,对吸附曲线作了线性拟合,确定了相应的平衡吸附率,在Cr3 初始浓度为1、5、10和20 mg/L时,木屑对Cr3 的平衡吸附率为81%、68%、56%和40%,花生壳依次为77%、63%、53%和42%,并探讨了这2种吸附剂对溶液中Cr3 的吸附机理.

| Abstract: | Study on the removal of Cr~(3+) from aqueous solution by sawdust and peanut husks.The effects of pH value,initial Cr~(3+) concentration and temperature on adsorption have been investigated,adsorption curves linear fit,ensured the correspondence equilibrium uptake for the two adsorbents.While the initial concentration of Cr~(3+) is 1,5,10,20 mg/L,the equilibrium uptake on sawdust is 81%,68%,56% and 40%,on peanut husks is 77%,63%,53%and 42% respectively.The adsorption mechanism is also discussed. |
