【摘要】 矿物腐殖质间的交互作用是土壤和水体沉积物及悬浮颗粒物中环境物质的重要界面过程。不管是氮、磷植物性营养元素还是有毒的重金属、有机物,它们在表生环境中的迁移转化与归趋受到矿物、腐殖质及其复合体的表面活性和迁移性的调控。矿物腐殖质体系的界面作用研究是前沿性的研究领域,主要目的是揭示矿物腐殖质复合体的结构特性(例如颗粒物的圈层结构与表面微形貌)及其与颗粒物表面活性的关系,进而揭示土壤和水体环境中矿物腐殖质间的交互作用规律。本文对该领域的研究现状进行评述,并提出未来可能的发展趋势更多还原

【Abstract】 Mineralhumus interactions are key interfacial processes for the environmental substances in soils, aquatic sediments and suspended particulates. The movement, transport and fate of either nutrient elements of nitrogen and phosphorus or heavy metals as well as toxic organic chemicals in the environment are regulated by the surface reactivity and movement of minerals, humic substances and their complexes. The research on the interface interactions of mineralhumus systems is a prospective field. The major objective in this study lies in describing such structural features of particulates as the layered structure and the micro_conformation and their relations with the reactivity of particulates and revealing the mechanism of mineralhumus interactions in soil and water environments. In this paper, the advances made in this field are reviewed and its future trend is predicted.更多还原
