Chapter

Abstract

Chemical methods aim at addition of chemicals or solvents into the polluted soils so as to stabilize the pollutants and convert them into less toxic forms that are harmless to the waterbodies, plants, and human beings. Since, complete soil remediation is difficult to achieve with biological methods alone hence, the amalgamation of both biological and chemical methods has gained much attention of the scientists. Besides that, the harmful effects of the use of chemical methods should also be considered before implementing on a pilot-scale. The materials generally used for chemical treatments are metallic oxides, clays or biomaterials. Remediation efficiency of these materials depends upon the soil texture, organic matter present in the soil, type of metal contaminant etc. Furthermore, chemical methods can offer a fast remediation compared to slow bioremediation process. This chapter discusses the available chemical remediation methods such as chemical leaching, chemical oxidation, chemical fixation and electro kinetic remediation.
