  • Effect Of Soil Washing With Biodegradable Chelators On

    Soil washing with chelators is a promising and efficient method of remediating metals-contaminated soils. However, the toxicity of residual metals and the effects on soil microbial properties have remained largely unknown after washing.

  • Remediation Of Diesel Contaminated Soils Using

    Soil washing using surfactants was innovated for soils contaminated with oil hydrocarbons. Clay content of the soil is a significant factor in washing because interfacial tension of the surfactant and clay will decrease surfactant concentration. First, contaminated one should be identified for in-situ washing since washing operations

    Tartaric acid with metal extraction yields typically following the sequence, copper nickel inc cadmium lead. Sequential extractions proposed by the European Communities Bureau of Reference method used to assess the redistribution of heavy metal forms in the soil showed that apparent metal mobilities were reduced upon soil washing.

  • Remediation Of Multiple Heavy Metalcontaminated

    The remediation of heavy metal-contaminated soils is a great challenge for global environmental sciences and engineering. To control the ecological risks of heavy metal-contaminated soil more effectively, the present study focused on the combination of soil washing (with FeCl 3) and in situ immobiliation (with lime, biochar, and black carbon).The results showed that the removal rate of Cd, Pb

  • Extraction Of Heavy Metals From Soils Using

    2018-8-18  Metal pollution of soils is widespread across the globe, and the clean up of these soils is a difficult task. One possible remediation technique is ex-situ soil washing using chelating agents. Ethylenediaminetetraacetic acid (EDTA) is a very effective chelating agent for this purpose but has the disadvantage that it is quite persistent in the environment due to its low biodegradability.

  • Remediation Of A Dieselcontaminated Soil From A

    Regarding the surfactant soil washing experiments, ionic surfactants showed removal rates above the control test of about 78.51 % (Maranil LAB), 71.27 % (Texapon 40), 60.13 % (SDS), and 48.19 % (Surfacpol G). In contrast, some nonionic surfactants showed removal rates below soil-washing background rate (40 %).
