This work studies the remediation of groundwater saturated with dense non-aqueous phase liquid (DNAPL) from lindane production wastes by electrochemical oxidation. DNAPL-saturated contains up to 26 chlorinated organic compounds (COCs), including different isomers hexachlorocyclohexane (HCH). To do this, polluted was electrolysed using boron-doped diamond (BDD) and stainless steel (SS) as anode cathode, respectively, influence current density on COCs removal evaluated in range 5 50 mA cm−2....
Soils contaminated with hexachlorocyclohexanes (HCHs) are a legacy of the heavy use lindane during 20th century. This pesticide production generated large amounts residues other HCH isomers, which were habitually mismanaged. The sediments treated in this work (coming from an old landfill) example environmental problem global dimensions. efficient remediation these sediments, mainly β-HCH (99 mg kg−1) and α-HCH (254 is still challenge. thermal activation persulfate (PS) required excessive...
The desorption of hydrophobic organic compounds (HOCs) and limited mass transfer in soil systems is a significant challenge for efficient remediation by oxidation treatments. utilization sonochemistry promising technology to enhance the decontamination HOCs-polluted soils. In this work, ultrasound (US) was coupled NaOH activating persulfate (PS) real polluted with hexachlorocyclohexanes (HCHs) (ΣHCHs = 404 mg kg−1). Batch experiments (mass aqueous/soil ratio, VL/WS 2) were performed evaluate...
This research studies the acute toxicity of real contaminated soils (topsoil and subsoil) with hazardous chlorinated organic compounds (COCs) from lindane manufacturing wastes. The Microtox® bioassay was used to determine (modified Basic Solid Phase Test), soil elutriates (Basic extracts (adapted Organic Solvent Sample Solubilization in which hydrophobic are soluble. these persistent contaminants (hexachlorocyclohexanes, HCH isomers, as particulate matter topsoil, COCs, dense non-aqueous...
This work evaluates the electrolysis of groundwater saturated with dense non-aqueous phase liquid (DNAPL) from lindane production wastes using mixed metal oxide (MMO) anodes to remove 26 Chlorinated Organic Compounds (COCs). Synthetic DNAPL an industrial landfill was employed, and influence current density (5–50 mA cm−2) studied. Results show that removing COCs DNAPL-saturated in 300 min is possible, reaching a final conversion 0.99 when densities 50 cm−2 are applied. Under these operating...
Abstract BACKGROUND The breakdown of imidazolium ionic liquids ( ILs ) by Fenton oxidation has been demonstrated, but using unaffordable doses hydrogen peroxide H 2 O ). literature studies so far do not report on the evolution total organic carbon TOC and ecotoxicity. Therefore, potential application process for degradation still remains an open question. This work investigates feasibility treatment aqueous effluents containing imidazolium‐based different structures, represented length alkyl...
The existence of soils contaminated with organochlorine pesticides represents a serious environmental problem. In this work, real soil hexachlorocyclohexanes (ΣHCH = 373 mg kg−1), persistent organic pollutants included in the Stockholm Convention, was remediated. Surfactants were used to enhance solubilization and activated persulfate (PS) oxidation degrade pollutants. Solubilization experiments performed evaluate effect surfactant (sodium dodecyl sulfate (SDS), Emulse-3® (E3) Tween-80®...
The LIFE SURFING Project was carried out at the Bailin Landfill in Sabiñánigo, Spain (2020-2022), applying Surfactant Enhanced Aquifer Remediation (SEAR) and In Situ Chemical Oxidation (S-ISCO) a 60-meter test cell beneath old landfill, to remediate contaminated aquifer with dense non-aqueous phase liquid (DNAPL) from nearby lindane production. project overcame traditional extraction limitations, successfully preventing groundwater pollution reaching river. spring 2022, two SEAR...
