【摘要】：采用甘蔗废渣吸附去除废水中的铬离子,在常温下考察p H、甘蔗废渣用量、粒径、铬初始浓度等对铬去除的影响及甘蔗废渣去除铬的动力学。结果表明,Cr(Ⅵ)和Cr(Ⅲ)的去除率随着甘蔗废渣用量的增加而增大,随着甘蔗渣颗粒大小的增加而减小,随着铬离子起始浓度的增加而减小。Cr(Ⅲ)的去除效果随p H的增大而增大,Cr(Ⅵ)的去除效果随p H的增大而减小。铬的去除行为符合准二级模型。甘蔗废渣对Cr(Ⅲ)比Cr(Ⅵ)有较高的吸附能力。为今后甘蔗废渣用于含铬废水的处理提供依据。
[Abstract]:The effects of pH, sugar cane residue dosage, particle size and initial chromium concentration on the removal of chromium from wastewater were investigated at room temperature. The kinetics of removal of chromium from sugarcane waste residue was also studied. The results showed that the removal rates of Cr (鈪，
