摘要
水环境中金属离子—腐殖质—矿物(或细菌)之间的相互作用能够显著影响金属离子在地质体中的迁移和归宿。本文综述了水环境中腐殖质对金属离子在矿物、微生物等表面吸附行为影响的研究现状,分析讨论了复合型表面的基本特点、腐殖质对金属吸附到矿物表面的影响因素、腐殖质影响细菌表面吸附金属离子的机理,以及对三相体系不同研究者的研究思路与结论等。
The interactions among aqueous metals, humic substances, mineral or bacterial surfaces can significantly affect mass transport in many geologic settings. This paper reviews the studies on the humic substances adsorbed by mineral and bacterial surfaces that effect the adsorption behavior of heavy metals in aquatic environments. We analyze the basic properties of the composite (humatemineral, humatebacterial) surfaces and the factors by which the humic substances affect the adsorption of metal ions onto mineral and bacterial surfaces. Also, the adsorption mechanism of ternary humatemetalmineral (or bacteria) system and research results as well as developing trends are summarized here.
