Study on optimal application of the ex-situ soil washing method to remove metals from polluted soil
Journal Title: Advances in Environmental Sciences - International Journal of the Bioflux Society - Year 2011, Vol 3, Issue 2
Abstract
Overcoming the concentration of heavy metals in soil due to various polluting activities becomes a major problem. Soil washing is a remediation method that uses water, inorganic or organic acids and chelating agents, becoming increasingly used for soil rehabilitation. Determination of the site`s characteristics is the most important factor which depends on the soil washing method. Extraction of heavy metals with the soil washing method is influenced by geological and hydrological characteristics, soil type and composition, pH, organic matter content, distribution of pollutants in soil, soil physical and chemical characteristics and pollution source. The present paper is a study on the conditions in which the extraction of metals from soil may be applied to obtain the best results and propose a suitable alternative site remediation method by washing for heavily contaminated soils with heavy metals existing in our country.
