铝与土壤之间的表面化学反应及其后果

80年代以来，由于酸雨的发生及其对农业生产和生态环境的危害，土壤酸化问题再次成为土壤化学研究的热点．铝离子的土壤化学行为是土壤酸化的根本原因，而铝的吸附是给离子的土壤化学行为的重要方面．因此．研究铝的吸附有助于提示土壤酸化的本质，为防治土壤酸化提供有益的信息．本文综述了近30年来铝离子吸附的研究进展．其中包括吸附性铝离子的形态；铝的吸附表面；阴离子对铝吸附的影响；铝吸附的机理；铝的吸附对土壤性质的影响等．

Surface Chemical Reactions between Aluminum and Soil and Its Consequences

Since 1980's, the problem of soil acidification have attracted the attention of Soil chemists again, because of the occuring of acid rain and its darnage to agriculture and environment-ecology. The chemical behavior of Al ions in soil is the fundamental reason for soil acidification, and the adsorption of Al is an important factor affecting chemical behavior of Al in soils. Thus the study of Al adsorption can be of helpful to discover the essence of soil acidification,and to provide useful information for prevention and remediation of soil acidification. The new progress in research of Al adsorption during last 30 years were reviewed in this article, including forms of adsorbed Al, adsorption surface of Al, the influence of anions on adsorption of Al, the mechanisms of Al edsorption, the influence of Al adsorption on soil properties, and so on.
