摘要/Abstract

通过粉末烧结法制备了多孔沸石球, 烧结温度为1100～1300 ℃, 烧结时间为1 h. 所用原料为天然斜发沸石粉末, 烧结所得多孔沸石球的直径为3～5 mm, 宏孔孔径约为1 mm, 抗压强度可达1.703×10⁶ Pa. 通过对比烧结前后沸石的X射线衍射谱和红外光谱, 对烧结机理进行了初步分析. 采用BET气体吸附法测得该多孔沸石的比表面积为7.053m⁶/g. 通过SEM 分析也观察到了该多孔沸石具有优良的大孔和宏孔结构. 在上述多孔沸石表面负载活性氧化铝, 得到了对砷离子具有较强吸附能力的活性氧化铝负载多孔沸石球, 并对其吸附机理进行了研究. 研究表明, 该沸石球在水处理方面有广阔的应用前景.

A new kind of multi-pore zeolite ball was prepared by powder sintering method at 1100～1300 ℃ for 1 h. Nature zeolite clinoptilolite was used as raw material. The diameter of sintered zeolite ball was 3～5 mm and the macro-pore diameter in the zeolite ball was about 1 mm. Compressive strength of the zeolite ball can reach 1.703×10⁶ Pa. Sintering mechanism was studied by comparing the XRD and IR patterns of nature zeolite and sintered zeolite. Specific surface area of the multi-pore zeolite ball was calculated by BET adsorption method as 7.053 m²/g. Plenty of macro-pores and meso-pores were observed on the multi-pore zeolite ball by SEM method. Activated alumina was supported on the ball and a kind of multi-pore zeolite ball which has a good ability in absorbing the As ions was prepared. The mechanism of As adsorption on multi-pore zeolite balls was also studied. Research shows that the activated alumina supported zeolite ball has a wide application prospect in waste water treatment.

Key words: multi-pore zeolite, powder sintering, activated alumina supported, As absorption
