removal of copper ions from contaminated soil by enhanced soil washing
this study investigated the feasibility of using different extracting solutions at various concentrations to remove copper from low permeability silty loam soils, which have a high buffering soil, ph of 7.6, where it spiked with copper at concentration of about 1500 mg/kg to represent soil conditions. the most efficient extracting solutions could be used as purging/extracting solutions in other...
متن کاملImproved removal of Trinitrotoluene (TNT) from contaminated soil by inducing aerobic process: kinetic and chemical byproducts
This study describes the biological degradation of TNT by using induced aeration. Three plastic reactors were used. In each reactor 3 kg of soil were used. In order to increase the porosity of the soil, sawdust was added to soil. Textile wastewater treatment plant sludge was also added to soil. TNT at the concentrations of 1000 mg/kg of soil was added thereafter. Rhamnolipid biosurfactant at th...
متن کاملSimultaneous Removal of Cadmium and Turbidity in Contaminated Soil-washing Water by Electroflotation
The removal of cadmium and turbidity from contaminated soil-washing water was studied by Electroflotation (EF) at the laboratory scale by using sodium lauryl sulfate (SLS) as an anionic surfactant, and calcium hydroxide (Ca(OH)2) as a coagulant. The stoichiometric cadmium to collector (SLS) and coagulant (Ca(OH)2) ratio was 1:4.5. Significant removal of cadmium (100 %, not detected in the resid...
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 کاملEDTA-enhanced phytoremediation of lead contaminated soil by Bidens maximowicziana.
Phytoremediation is a potential cleanup technology for the removal of heavy metals from contaminated soils. Bidens maximowicziana is a new Pb hyperaccumulator, which not only has remarkable tolerance to Pb but also extraordinary accumulation capacity for Pb. The maximum Pb concentration was 1509.3 mg/kg in roots and 2164.7 mg/kg in overground tissues. The Pb distribution order in the B. maximow...
