摘要
利用一种具有多孔结构的生物玻璃材料,吸附水溶液中的四环素。结果表明,该材料对水溶液中的四环素有吸附作用,50 min后达到吸附平衡,平衡后的四环素去除率约为65%。吸附过程符合准二级动力学模型,符合Langmuir等温吸附模型。材料对四环素的去除效果随着四环素初始浓度的增加而下降,随着温度的上升而略有提高。
A porous bioglass material was used to adsorb tetracycline in water.The results showed that the material could adsorb tetracycline in the water and achieved equilibrium after 50 min adsorption with the removal effect at about 65%.The adsorption process accorded with the pseudo second order kinetic model and Langmuir isotherm model.The removal effect in aqueous solution decreased with the increase of initial concentration of tetracycline,and increased slightly with temperature.
