| Abstract: | Low-molecular-weight (LMW) organic acids exist widely in soils and play an important role in soil processes such as mineral weathering, nutrient mobilization, and detoxification of Al. This article reviews the adsorption of LMW organic acids by variable charge soils and minerals, and the effects of these organic acids on surface charges, electrokinetic properties, and adsorption of inorganic ions by variable charge soils. The contents of the paper can serve related soil researchers as a useful reference. |
