摘　　要：在传统水热合成法基础上,采用导向剂法进行改性,合成出超微5A分子筛,通过XRD、SEM、FT-IR等多种方法进行表征。同时探讨了时间、pH值和温度等因素对超微5A沸石分子筛吸附废水中苯酚性能的影响,并提出了优化吸附条件。本研究对提高废水中苯酚的处理效果具有很好的参考价值。Zeolite, a porous material with large specific surface area and pore volume, was anideal adsorbent in wastewater treatment. In the study, 5A zeolite was synthesized in thetraditional method, and then modified by the guide agent method to prepare ultramicro 5Azeolite molecular sieve. And the final products were characterized by XRD, SEM, FT-IR andother methods. The effect of adsorption time, pH, adsorption temperature and other conditionson adsorption performance of phenol in the wastewater by ultrafinamicro 5A zeolite molecularsieve was discussed, and the optimal adsorption conditions were determined. This work washelpful to improve removal efficiency of phenol in wastewater.
