Decontamination 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 کاملSoil Washing to Remove Mixed Wastes
Objective The goal of this laboratory exercise is to acquaint students with some of the chemical reactions that result in the binding of inorganic and organic pollutants in subsurface materials. Extractants used by engineers to release contaminants at hazardous waste sites (where mixtures of both types of contaminants are present) may or may not prove effective, depending upon their mechanism o...
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...
متن کاملRemediation of Cadmium-contaminated Paddy Soils by Washing with Ferric Chloride (FeCl3): Effect of Soil Washing on the Cadmium Concentration in Soil Solution and Spinach
We evaluated the effects of soil washing with ferric chloride (FeCl3) on cadmium (Cd) concentrations in soil solutions and Cd absorption by two spinach cultivars in pot experiments. Soil samples were collected from washed and unwashed plots of rice paddy fields in Fukuoka and Toyama, Japan. Spinach pot cultivation was performed with the above mentioned soil under oxidative conditions. Before an...
