摘    要:研究了活性炭在酸(HNO3,H2SO4,HCI)和碱(NaOH,氨水)处理后对苯酚吸附性能的影响,测定了活性炭的亚甲基蓝值、碘值扣表面官能团等基本物理化学参数。研究发现:碱改性使活性炭上酸性官能团数量减少。碱性官能团增加,增强了活性炭对苯酚类疏水性物质的吸附客量。NaOH、氨水改性活性炭对苯酚的吸附值比未改性活性炭分别提高了56,70%和47.40%。

关 键 词:活性炭  改性  苯酚  吸附

Abstract:Effect of activated carbons modified by acids(HNO3,H2SO4,HCl) and alkalis(NaOH,ammonia) on the adsorption of Phenol was evaluated.Methylene blue adsorption/d Iodine adsorption and surface chemical functional groups of activated carbons were determined.The results reveal that more alkali groups could be produced on the surface of activated carbons modified by alkalis and acid groups reduced.These alkali groups could improved the adsorption capacity of activated carbons.The adsorption of phenol on the activat...
Keywords:activated carbon  phenol  modification  adsorption
