【摘要】 考察了测定活性炭表面酸性基团方法的影响因素，测定了几种活性炭表面酸性基团的数量，初步研究了苯酚和苯甲酸在活性炭上的吸附与活性炭表面酸性基团的数量、种类之间的关系，结果表明：苯酚和苯甲酸在活性炭上的吸附在相当程度上受活性炭表面酸性基团的数量与种类的影响；苯酚的吸附量，随活性炭单位表面上酚羟基和羧基数量的增加而降低；而苯甲酸的吸附则与炭表面的酸性基团总量有关。更多还原

【Abstract】 Effcet of measurement of the acidic groups in activated carbons surface on their adsorption behaviours were studied. The quantity in acidic function groups were measured.The relationship of adsorption for phonel and benzoic acid on activated carbons between the quantity and kinds of the acidic groups on activated acid surface were studied.It is pointed out that the adsorption for phonel and benzoic acid on activated carbons is effec led by the quantity and kinds of acidic groups on activated carbon surface.The results also show that adsorption of benzoic acid is related to the total acidity on the carbons surface.The amount of phenol adsorbed on carbon surface increases along with the increases of the amout of carboxylic and hydrooxyl groups per unit of carbon surface area.更多还原
