This paper reports the physicochemical properties that describe the adsorption of a series of solutes onto the surfaces of amorphous carbon blacks. Adsorption was studied at concentrations that correspond to low surface coverages and in the presence of volatile solvent diluents. The adsorbates and adsorbents were selected for their relevance as models for environmental agent-particle complexes originating from incomplete combustion. The data clearly show that the major factors that determine the strength of adsorption are the surface properties of the adsorbent and the intermolecular forces between the surface and the adsorbing molecule. The heat of adsorption data have been used to predict the lifetime of the absorbate-adsorbent complexes.
本文报道了描述一系列溶质在无定形炭黑表面吸附的物理化学性质。吸附研究是在对应于低表面覆盖率的浓度下以及挥发性溶剂稀释剂存在的情况下进行的。选择被吸附物和吸附剂是因为它们作为不完全燃烧产生的环境介质 - 颗粒复合物模型具有相关性。数据清楚地表明，决定吸附强度的主要因素是吸附剂的表面性质以及表面与吸附分子之间的分子间力。吸附热数据已被用于预测被吸附物 - 吸附剂复合物的寿命。
