remediation of earth resources contaminated with arsenic using soil washing technique
development of industrial activities around the world, especially during the last decades has resulted in environmental pollution rising. soil pollution is always considered as one of the most dangerous environmental threat for human’s life, fauna and flora. heavy metals such as arsenic are potential hazardous elements in generating the soil pollution. these materials could be entered into the ...
متن کاملDecontamination Experiment of Plant Soil Using Soil Washing Method
In Korea, there are not detailed analysis data on soil contamination in nuclear power plant(NPP) and suitable treatment criteria of contaminated soils. When the soils of NPP were contaminated, they have been simply collected and kept in radioactive waste building. But contamination of soils in NPP is inevitable and enormous amounts of contaminated soils can be produced during decommissioning. T...
متن کاملRemediation of Nitrobenzene Contaminated Soil by Combining Surfactant Enhanced Soil Washing and Effluent Oxidation with Persulfate
The combination of surfactant enhanced soil washing and degradation of nitrobenzene (NB) in effluent with persulfate was investigated to remediate NB contaminated soil. Aqueous solution of sodium dodecylbenzenesulfonate (SDBS, 24.0 mmol L-1) was used at a given mass ratio of solution to soil (20:1) to extract NB contaminated soil (47.3 mg kg-1), resulting in NB desorption removal efficient of 7...
متن کاملA lysimeter station for contaminated soil studies
A lysimeter station has been set up by AMRA for the study of the reactive transport of contaminants in soil at the field-scale. It consists of eight lysimeters that can operate individually and simultaneously. Each lysimeter is a steel cylinder (diameter 1.14m, height 2m) filled with an undisturbed soil monolith, whose upper surface is directly exposed to the external environmental agents. A se...
متن کاملUsing poly-glutamic acid as soil-washing agent to remediate heavy metal-contaminated soils.
The extraction efficiency of heavy metals from soils using three forms of gamma poly-glutamic acid (γ-PGA) as the washing agents was investigated. Controlling factors including agent concentrations, extraction time, pH, and liquid to soil ratio were evaluated to determine the optimum operational conditions. The distribution of heavy metal species in soils before and after extraction processes w...
