Abstract

Abstract

Atrazine is a typical environmental hormone and iron oxide which is one of the major components in the soil minerals. Studying of iron oxide on the adsorption behavior of atrazine facilitates the understanding of acts of environmental hormones in the environment. In this paper, the effects of the atrazine polluted soil and mixture of iron oxides on the adsorption and desorption of atrazine is studied, and three different ratios of soil and a mixture of iron oxides on the atrazine desorption are investigated. In addition, the main factors are found by means of changing factors such as desorption time, temperature, and pH value. Results show that temperature, pH, ratio of iron oxides and soil all affect the desorption in different degrees. Dynamic equilibrium of the effect of the mixture on the desorption could be achieved in about 4 hours generally. Acid or alkaline environment and the appropriate temperature enhance the desorption, and the mixture obviously has better desorption effect than the original soil.
