摘要
自制得到磁性Fe3O4/Beta沸石复合材料,并通过SEM、XRD、FT IR,磁滞回线表征鉴定,相应最佳吸附除磷实验条件为:0.05g磁性Fe3O4/Beta沸石复合材料对5mL,50mg/L PO34-溶液(pH值为3.0)吸附率近100%,吸附平衡时间为6h,吸附行为符合Freundlich方程,可在碱性介质溶液中脱附再生。磁性Fe3O4/Beta沸石复合材料基于磁基质易于水体分离操作,过程简便可控,实际应用前景广阔。
The magnetic Fe304/Beta zeolite composite material was prepared and characterized by SEM, XRD, FT IR and magnetic hysteresis loop method. The related adsorptive experiments showed that after0.05 g magnetic Fe3O4/Beta zeolite composite was added into 5 mL 50 mg/L PO34- solution （pH 3.0） through 6h contacting time, the phosphorus removal efficiency could reach nearly 100%. The adsorptionbehavior fit With Freundlich adsorption isotherm. The saturated composite could be regenerated through alkaline solution media. The Fe3O4/Beta zeolite composite had the advantages of being easily isolated from aqueous solution. The process was controllable and convenient, and it possessed great potential in practice.
