Abstract

Novel anion-exchange resins were prepared from asphaltenes by nitration with nitric acid followed by reduction of the nitrated asphaltenes with sodium sulfide. The aminated asphaltenes were investigated as anion exchange resins for the treatment of phenol-containing wastewater. Their maximum adsorption capacity was found to be 2.3-fold superior to that of an industrial AV-17-8 (OH^– form) AER sample.

沥青质阴离子交换树脂的制备及其在处理含酚废水中的吸附能力

摘要

由沥青质通过用硝酸硝化，然后用硫化钠还原硝化的沥青质来制备新型阴离子交换树脂。研究了胺化沥青质作为阴离子交换树脂处理含酚废水的方法。它们的最大吸附能力被发现是2.3倍优于工业AV-17-8（OH的^-形式）AER样品。
