Study on physical and chemical properties of three different kinds of soils and their adsorption behavior of copper ion

  • Received Date: 2020-02-27
  • The basic physical and chemical indicators such as pH value,organic matter content,free iron oxide content,soil mechanical composition,cation exchange capacity of the three kinds of soils in different regions were measured,and the kinetics of the three kinds of soils adsorbing Cu2+ in wastewater were studied.The results showed that red soil was acidic and had the highest free iron oxide content,black soil was neutral and its cation exchange capacity was the highest,brown soil was neutral and its organic matter content was the highest;compared with red soil and brown yellow soil,the adsorption process of black soil on Cu2+ was more in line with the second-order kinetic equation and more suitable for Cu2+ adsorption material.
