【摘要】 本文系统地研究了几种不同来源的天然大分子有机物质,如腐植酸、富里酸及丹宁等对活性炭吸附微量有机污染物苯酚、2,4-二氯苯酚的影响。发现腐植质在活性炭表面上的竞争吸附效应与其腐植化程度有密切关系,并探讨了金属离子对腐植质竞争吸附效应的影响。更多还原

【Abstract】 The competitive effects of naturally occuring organic matters such ashumic acids, fuivic acid and tannic acid from different sources on theadsorption of trace phenol and 2 , 4 -dichorophenol by activated carbonhave been systematically studied. It is shown that the degree of competitiveeffects is closely related to their humification extent. The effect ofpresence of metal ions on the degree of competitive adsorption is alsodiscussed.更多还原
