| 摘 要： | 以正硅酸乙酯为硅源、偏铝酸钠为铝源、四丙基氢氧化铵为模板剂,利用水热合成法制备ZSM-5沸石分子筛并将其应用到吸附水中对苯二酚的研究,考察了吸附时间、对苯二酚溶液pH值、吸附温度、吸附剂用量对吸附效果的影响。结果表明,最佳吸附条件是:吸附温度为35℃,吸附时间为60 min,对苯二酚溶液pH值为6,吸附剂用量为0.4 g。此时,对苯二酚的去除率最高,达到了68.28%。

| Abstract: | ZSM-5 Zeolites have been synthesized with hydrothermal synthesis method using tetraethyl or-thosilicate as silica source,sodium aluminate as aluminum source,tetraProPyl ammonium hydroxide as temPlating agent. The effect of adsorPtion temPerature,adsorPtion time,PH value of hydroquinone solution and adsorbent dosage on adsorPtion were investigated. The result showed that oPtimum conditions were as follows：adsorPtion temPerature was 35 ℃,adsorPtion time was 60 min,PH value of hydroquinone solution was 6,adsorbent dosage was 0. 4 g. The removal rate of hydroquinone was 68. 28% under the above con-ditions. |
