电子导电炭黑样品（Lion Akzo Co.）用硝酸、过氧化氢、干燥空气或氢气进行处理。除了用硝酸处理的样品外，这些样品具有几乎相同的比表面积和孔体积。为了研究这些处理过的样品的吸附机理，进行了苯酚气体吸附和水相吸附。在水相吸附过程中，吸附的苯酚量随着碳样品表面氧化合物数量的减少而增加。在气体吸附过程中，吸附的苯酚量随着碳表面含氧化合物数量的减少而减少。苯酚残留量也减少。在气体吸附的情况下，不仅碳上的疏水位点与苯酚的疏水基团之间发生相互作用，而且碳上的表面官能团与苯酚的亲水基团之间也发生相互作用。在水相吸附的情况下，竞争...
Samples of electronic conductive carbon black (Lion Akzo Co.) were treated with nitric acid, hydrogen peroxide, dried air, or hydrogen gas. These samples had almost the same specific surface areas and pore volumes, except for the one treated with nitric acid. Phenol gas adsorption and aqueous-phase adsorption were carried out in order to study the adsorption mechanism on these treated samples. During aqueous-phase adsorption, the amount of phenol adsorbed increased with a decrease in the number of surface oxygen compounds on the carbon sample. During gas adsorption, the amount of phenol adsorbed decreased with a decrease in the number of oxygen compounds on the carbon surface. The residual amount of phenol also decreased. In the case of gas adsorption, interactions occur not only between the hydrophobic sites on the carbon and the hydrophobic groups of phenol, but also between the surface functional groups on the carbon and the hydrophilic groups of phenol. In the case of aqueous-phase adsorption, competi...
