【摘要】 研究了具有不同结构特征的腐殖酸与多环芳烃蒽的结合强度与腐殖酸分子中的核心官能团含量及酸度变化的关系。结果表明,腐殖酸溶液与蒽的结合常数KOC与UV254/TOC的变化呈现出很好的相关性;各腐殖酸溶液与多环芳烃蒽的结合常数KOC随酸度的增强而增强。说明腐殖酸与多环芳烃之间作用的核心可能在腐殖酸类物质的苯环上,腐殖酸的酸性基团参与了腐殖酸与多环芳烃之间的作用。更多还原

【Abstract】 The relation between the bonding strength of HAs and PAHs and content of the aromatic rings as well as acidity were explored.The results show that the bonding constant between HAs and PAHs has good correlation with the change of UV254 /TOC,and the bonding constant increases with increase of solution acidity.So the aromatic rings must be the core functional group in interaction of HAs and PAHs,and the acidic groups in HAs molecule must take part in the interaction between HAs and PAHs.更多还原
