| 摘 要： | 以蒙脱石(MMT)和硫酸铜为主要原料,制备了载铜蒙脱石(MMT-Cu),并对MMT-Cu吸附大肠杆菌K88的能力进行比较研究.结果表明:MMT和MMT-Cu对大肠杆菌K88均有较强的吸附作用,但载铜后蒙脱石吸附大肠杆菌的能力明显增强.细菌与吸附材料作用90min后可达到吸附平衡.介质pH值、离子强度和吸附温度对MMT和MMT-Cu吸附细菌的能力均有不同程度的影响.

| Abstract: | The adsorption capacity of Cu2+-loaded montmorillonite(MMT-Cu) for Escherichia coli K88 was investigated and compared to the adsorption of E.coli K88 on montmorillonite alone(MMT).MMT-Cu was prepared from MMT and CuSO4.Both MMT and MMT-Cu had a strong adsorption capacity for E.coli K88,but the adsorptive capacity of MMT-Cu for E.coli K88 was higher than that of MMT.The adsorption processes between E.coli K88 and either MMT or MMT-Cu reached equilibrium after 90 mins.Temperature,pH,and ionic strength in the ... |
