Gallic Acid Derived Organogels: Removal of Organic Pollutants in Water

摘要/Abstract

摘要：

合成了3种结构新颖的没食子酸衍生物有机凝胶因子,研究了该类有机凝胶对水中煤油、柴油、罗丹明 B、亚甲基蓝等4种有机污染物的去除、回收方面的性能.结果表明,水中的煤、柴油均可通过凝胶化去除,并可实现对煤油或柴油与有机凝胶因子的双回收;有机凝胶对水中罗丹明 B、亚甲基蓝具有明显净化作用,特别是通过自制的凝胶柱可实现快速水净化,分离时间约5 min.罗丹明 B、亚甲基蓝的去除率均达94.0 %以上.

Abstract：

Three novel gelators based on gallic acid were synthesized, and their remove performance and recovery for four kinds of organic pollutants, such as kerosene, diesel, rhodamine B, and methylene blue in water were studied respectivly. The results showed that both kerosene and diesel in water can be removed by gelation, and the kerosene or diesel and gelator can be both recovered easily. Actually, the organogel also displayed obvious purification effect on rhodamine B or methylene blue in water, especially self-made gel column that can achieve water purification rapidly(about 5 minutes). The removal rates of rhodamine B and methylene blue can reach more than 94.0 %.
