高活性活性炭的制备和应用研究

以农业废弃物果壳(花生壳、核桃壳)为原料制备应用于治理废水中持久性有机污染物的高活性活性炭。研究制备方法和吸附工艺参数对材料吸附容量的影响。实验表明,以果壳为原料制成的高活性活性炭对合成染料、芳香族胺类和酚类的饱和吸附容量分别为:阳离子蓝染料123 mg/g、苯胺5.7 mg/g和苯酚3.5 mg/g,具有优良的吸附能力。

Studies on the Preparation and Application of Highly Adsorptive Activated Carbon

Agricultural waste materials(the shell of peanuts and drupes) can be used as raw materials to produce a highly adsorptive activated carbon which can dispose of persistent organic contaminations in wastewater.The effects of preparation methods are studied as well as the technological parameters on the adsorption capacities.The results of the experiment show that the saturated adsorption capacities of highly adsorptive activated carbon toward synthetic dye,aromatic series amine and hydroxybenzene are: Cation Blue Dye 123 mg/g,phenylamine 5.7 mg/g,phenol 3.5 mg /g.The highly adsorptive activated carbon prepared has great adsorption capacity.
