Adsorption characteristics of cadmium onto aggregates of various acidic red soils from South China

Purpose Particle size poses important influence on the adsorption and enrichment of heavy metals in soil aggregates. In this study, we conducted adsorption experiments to compare the effect of particle size on the adsorption behavior of cadmium (Cd) in aggregates of soils with different properties....

Zusammenfassung:	Purpose Particle size poses important influence on the adsorption and enrichment of heavy metals in soil aggregates. In this study, we conducted adsorption experiments to compare the effect of particle size on the adsorption behavior of cadmium (Cd) in aggregates of soils with different properties. Materials and methods Eight types of acid red soils sampled from South China were partitioned into aggregates of different particle sizes (2–0.25, 0.25–0.05, and
