Preparation of Bamboo Charcoal Supported Al3+ and Study on Its Adsorption and Catalytic Activity of p-nitrophenol

Abstract

竹炭是竹材热解得到的主要产品,是一种在环境保护、医学和食品等领域具有广阔应用前景的新型吸附材料。但由于生产工艺等问题,直接将竹炭应用于废水处理存在吸附容量小,吸附选择性差等问题,所以对竹炭进行各种处理以期提高其吸附性能越来越受到人们的关注。用作农药、医药和染料生产原料的对硝基苯酚(p-nitrophenol,PNP)是一种高毒性、很难被生物降解的有机物,从生产排放的废水中去除对硝基苯酚有多种方法,其中吸附法由于不引人新的污染物,且能从废水中分离有机污染物,实现废物回收再利用,因而在水处理中得到广泛应用。 本文采用常温下,通过简单而经济的湿法浸渍,制得Al3+/竹炭。考察了Al3+/竹炭的制备...Bamboo charcoal is the main product from bamboo pyrolysis and a new adsorptive material with wide prospective in areas of environment protection, medical and food industry. However, owing to the low level of manufacturer technology, there are some problems with using bamboo charcoal directly to treat wastewater, such as small adsorption properties, bad adsorption selectivity. Therefore treating b...学位:工学硕士院系专业:化学化工学院化学工程与生物工程系_化学工程学号:2062006115202
