Remediation 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 for Remediation of Non Volatile Hydrocarbon Polluted Soils
This paper illustrates the possibilities of applying what is essentially a physical soil-washing technique for treatment of soil contaminated by semi-volatile hydrocarbons in order to reduce the level of pollution to that permitted by Italian regulations. The ground around a factory producing lubricating-oil additives consists of silty-sandy soils, which have long been contaminated by heavy hyd...
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...
متن کاملRemediation of toxic metal contaminated soil by washing with biodegradable aminopolycarboxylate chelants.
Ex situ soil washing with synthetic extractants such as, aminopolycarboxylate chelants (APCs) is a viable treatment alternative for metal-contaminated site remediation. EDTA and its homologs are widely used among the APCs in the ex situ soil washing processes. These APCs are merely biodegradable and highly persistent in the aquatic environments leading to the post-use toxic effects. Therefore, ...
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...
