近十几年来,对可变电荷土壤基本性质的研究。受到世界土壤科学界越来越多的关注。可变电荷土壤含有相当数量的铁铝氧化物,除带有多量的可变负电荷外,其正电荷比恒电荷土壤也多得多,阴离子吸附现象明显,吸附机理复杂,因此人们除了研究阴离子在铁铝氧化物上的吸附外,也开始研究阴离子在可变电荷土壤上的吸附。本文就土壤及土壤物质对某些阴离子的专性吸附,包括研究技术、吸附状况,吸附机理及吸附后对表面性质的影响等予以综述,以期有助于在我国进一步开展这方面的研究工作。
In the last ten years, the basic properties of variable charge soils have been studied. By the world soil science community more and more attention. Variable charge soil contains a considerable amount of iron-aluminum oxide, with a large amount of variable negative charge, the positive charge is much more than constant charge soil, anionic adsorption phenomenon is obvious, the adsorption mechanism is complex, so in addition to studying the anion In addition to the adsorption on Fe-Al oxides, the adsorption of anions on variable charge soils has also been studied. In this paper, the specific adsorption of some anions on soils and soil substances, including research techniques, adsorption conditions, adsorption mechanism and the influence on the surface properties after adsorption, are reviewed in this paper in order to help further carry out research in this area in our country.
