Emerging organic contaminants are one of the main threats to the environment and society. The primary source of these contaminants in the environment is wastewater treatment plants (WWTPs) that cannot eliminate all of these compounds. Pharmaceutically active compounds (PhACs) deserve special attention as new substances are constantly being developed, and the number of these compounds that reach consumers is increasing. The consequences of PhACs to human health are not yet subjected to regulatory criteria or norms; nevertheless, chronic toxicity in biodiversity has already been reported. In response to global environmental concerns, there has been increasing interest in sustainable solutions to remove these compounds from effluent in WWTPs. Electrochemical technologies developed for effluent treatment were designed to promote PhAC degradation and safe effluent discharge. Understanding the relationship between different anode characteristics and electrochemical oxidation performance is essential for developing a cost‐efficient technology to remove contaminants from wastewater. In this context, the performance of graphite and platinized electrodes were compared in the electrochemical oxidation of selected emerging organic contaminants in a recirculating flow reactor. proof epub_ahead_of_print

Oil is one of the more toxic pollutants in the environment. Due to the fragility of the Arctic environment to anthropogenic disturbances, the persistence and severity of ecological impacts from oil spills can be significant. The development of non‐invasive and sustainable solutions for soil remediation is a pressing problem. The feasibility of electrokinetic technology as a remediation strategy to enhance oil removal from soil under cold climate conditions was assessed. The soil was collected in Sisimiut, Greenland from a dump site after an oil spill. A range of temperatures and different strategies for applying electric current were tested in experiments over 14 days. The soil showed a total petroleum hydrocarbon concentration of 69 500 mg kg−1, and the levels decreased between 43% and 78%. The effect of the electric field for oil removal was not verified when compared with controls. Naturally cold‐adapted microorganisms seemed to have a strong influence on oil remediation under the tested conditions. proof epub_ahead_of_print

Electrokinetic Remediation for Environmental Security and Sustainability Explore this comprehensive reference on the remediation of contaminated substrates, filled with cutting-edge research and practical case studies Electrokinetic Remediation for Environmental Security and Sustainability delivers a thorough review of electrokinetic remediation (EKR) for the treatment of inorganic and organic contaminants in contaminated substrates. The book highlights recent progress and developments in EKR in the areas of resource recovery, the removal of pollutants, and environmental remediation. It also discusses the use of EKR in conjunction with nanotechnology and phytoremediation. Throughout the book, case studies are presented that involve the field implementation of EKR technologies. The book also includes discussions of enhanced electrokinetic remediation of dredged co-contaminated sediments, solar-powered bioelectrokinetics for the mitigation of contaminated agricultural soil, advanced electro-fenton for remediation of organics, electrokinetic remediation for PPCPs in contaminated substrates, and the electrokinetic remediation of agrochemicals such as organochlorine compounds. Other topics include: A thorough introduction to the modelling of electrokinetic remediation An exploration of the electrokinetic recovery of tungsten and removal of arsenic from mining secondary resources An analysis of pharmaceutically active compounds in wastewater treatment plants with a discussion of electrochemical advanced oxidation as an on-site treatment A review of rare earth elements, including general concepts and recovery techniques, like electrodialytic extraction A treatment of hydrocarbon-contaminated soil in cold climate conditions Perfect for environmental engineers and scientists, geologists, chemical engineers, biochemical engineers, and scientists working with green technology, Electrokinetic Remediation for Environmental Security and Sustainability will also earn a place in the libraries of academic and industry researchers, engineers, regulators, and policy makers with an interest in the remediation of contaminated natural resources. proof inpress
