Soil 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 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 کاملRemoval of alkylphenols from polluted sites using surfactant-assisted soil washing and photocatalysis.
BACKGROUND AND PURPOSE Surfactant-assisted soil washing and photocatalysis are well-known remediation processes of environmental concern. The application of photocatalysis to treat soil washing extracts containing 4-methylphenol, 4-ethylphenol and 4-tert-butylphenol in the presence of nonionic (C(12)E(8) and C(12)E(23)) and anionic (SDS) surfactants and some of their binary mixtures was investi...
متن کاملMathematical modeling and optimization of sonication remediation of soil polluted with 2-methylpropane-2-thiol
Existence of 2-methylpropane-2-thiol as an organosulfur and odorant compound in the soil could causes environmental problem and social dissatisfaction. In this study, remediation of this type of thiol using ultrasound is investigated. Central Composite Design (CCD) based on Response Surface Model (RSM) was used to obtain effects of the main factor (Power, sonication time and amount of water) an...
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...
