摘要
In order to study the static adsorption of cadmium in the soil under the natural conditions,typical paddy soils in Chengdu area were sampled and simulated acid rain solutions containing mainly anions and cations with various pH values were prepared.Study and analysis revealed the adsorption characteristics of cadmium in the paddy soil,determined the key factors affecting adsorption behaviors of cadmium in the soil under acid rain.The sorption isotherm of cadmium in soil was established and fitted to the balance model in the concentration range of the experimental setting.It was showed that the Freundlich and Henry models had a better underlying index,and the two models can be used to describe the adsorption process of cadmium in the test soil.
