摘要
用稀硝酸和氢气对活性炭试样进行了表面改性处理。测定试样的孔隙性能、表面化学性能，以及试样对苯酚、苯磺酸水溶液的吸附等温线得知，经表面改性处理后，活性炭的孔隙性能无明显变化，而表面化学性能及对苯酚和苯磺酸的吸附等温线却发生了显著变化．从而说明了活性炭表面化学性质对吸附的影响。
The surface of activated carbon was treated and modified by 6 mol·L￣(-1) HNO_3 and H_2. Poreproperty,surface chemical property,and the adsorption isotherms of phenol and benzene sulfonic acid onsamples in aqueous solution were measured.It was found that,after the modification of the surface,therewas no significant change in pore property observed,but the chemical property and adsorption isothermchanged remarkably which indicates the influences of the chemical property upon adsorption.
