摘要 目的：研究Cu2+离子掺杂的新型介孔材料T12Cu-MP对四环素的吸附行为。方法：考察吸附时间、吸附温度、溶液pH值、初始浓度、离子强度对四环素在T12Cu-MP上吸附量的影响。结果：T12Cu-MP对四环素的吸附约需12h 达到吸附平衡，吸附量达97.36（mg/g）；四环素在T12Cu-MP上的吸附量随温度的升高而降低，并且降低的趋势很显著；T12Cu-MP对四环素的吸附受pH影响，pH7条件下吸附量最大；T12Cu-MP对四环素的吸附量随着初始浓度的增加而增加；T12Cu-MP对四环素的吸附量随着离子强度的增加而下降。结论：新型介孔材料T12Cu-MP对四环素有较好地吸附效果，可用于吸附脱除水体中四环素。

Abstract：Objective:To study on a new mesoporous materials of T12Cu-MP left on the water adsorption behavior of tetracycline.Methods: To observe the effect of adsorption time, adsorption temperature, pH value of the solution, the initial concentration, the ionic strength on the adsorption amount of tetracycline by T12Cu-MP. Results:T12Cu-MP on tetracycline adsorption needs 12h to reach adsorption equilibrium,adsorption capacity of 97.36 (mg/g);Adsorption effect on the T12Cu-MP of tetracycline and decreases with the increase of temperature, and the decreasing trend is very obvious;The adsorption amount of T12Cu-MP for tetracycline is influenced by pH,and it adsorbs the largest amount under pH7;Adsorption amount of T12Cu-MP for tetracycline increases with increasing initial concentration;The adsorption amount of T12Cu-MP for tetracycline decreased with increasing ionic strength.Conclusion:The new mesoporous materials of T12Cu-MP left on the water has better adsorption effect of tetracycline,and T12Cu-MP can be used to remove water adsorbed tetracycline.
