In this study, removal of Cr(Ⅵ) from synthetic groundwater by adsorption onto commercial activated carbon (CAC) made up of coconut shell is investigated in batch studies. Surface modification of CAC with sulfuric acid is also conducted to evaluate its removal performance. It is evident that CAC chemically modified with sulfuric acid (sulfuric-treated CAC) demonstrates higher Cr(Ⅵ) removal efficiency than non-treated CAC in dealing with contaminated groundwater with the pH is about 7.0, suggesting that sulfuric-treated CAC is suitable for the in-situ remediation of Cr(Ⅵ) contaminated groundwater. Adsorption of Cr(Ⅵ) is strongly affected by pH, the granular sulfuric-treated CAC exhibits the highest Cr(Ⅵ) adsorption capacity at pH 1.5 and the maximum Cr(Ⅵ) adsorption capacity of which estimated with the Langmuir model was 8.24mg/g.

The combination of electrokinetic remediation and permeable reactive barrier (EK-PRB combined remediation technology) is a new green technology for in-situ removal of soil and groundwater pollutants. This technology combines the advantages of electrokinetic remediation and permeable reactive barrier technology, and can deal with different types of organic and inorganic pollutants. It has the characteristics of convenient installation, simple operation, no secondary pollution, etc., and has broad development and application prospect. This paper introduces the technical principle of EK-PRB, summarizes the latest research results on the remediation of heavy metal, organic matter and nitrate contaminated soil and groundwater by the electrokinetic remediation and PRB. Finally,the technical problems of combinated remediation were pointed out, and development and application direction of this technology was noted.
