A review is presented of the study on sorption processes of copper ion in soils, discussing mainly sorption velocity, sorption isotherm, surface complexation models and factors affecting sorption rate. There are mainly two methods for measuring sorption velocity of copper in soil at present: 1) plotting curves of sorption capability varying with time, based on experimental data and studying gradients of the plotted curves for dynamics of the sorption; and 2) selecting experiential chemical dynamic equations to fit the data and picking out an optimum equation according to the principle of higher correlation coefficient and lower standard error, to carry out quantitative research based on sorption rate coefficient. With regard to quantitative description of copper sorption in soil, the experiential equation of sorption isotherm remain to be a very useful method; Considering effects of soil properties and environmental factors on the sorption, these parameters should be added into the model, making it better reflect the sorption process of copper ion in soil; however, little has been reported on this aspect, relatively. And not much has been done on influence of soil surface charge characteristics, and low molecular organic acid on copper sorption in soil and change in from of copper in the sorption process, either.
