Special Issue Information

Dear Colleagues,

Water is the integral and essential part of all life in the biosphere; however, natural and manmade distortion of water bodies can lead to water degradation and poses a serious risk of water scarcity and waterborne diseases. Developing novel technologies for the remediation of household, industrial, and agricultural waste water and evaluating its quality in terms of its reuse in other potential fields has attained great research interest. The resulting research efforts, paired with the recent successes regarding electrochemical technologies in clinical analysis, self-health monitoring, air sensing and purification, food and drug analysis, pollutant monitoring, etc., have led to the adoption of electrochemical technologies in water remediation and quality assurance and have propelled  innovation in this field to new highs. This Special Issue aims to showcase research papers, short communications, and mini-reviews that highlight new inventions in the field of electrochemical technologies for water remediation and quality assurance.

Abstract
Plastics are vital for society, but their usage has grown exponentially and contributes to the growth of pollution worldwide. The World Health Organization, WHO, already reported that microplastics (MPs) are found everywhere, in waste and fresh water, and in the air and soil. [...] Read more.
Plastics are vital for society, but their usage has grown exponentially and contributes to the growth of pollution worldwide. The World Health Organization, WHO, already reported that microplastics (MPs) are found everywhere, in waste and fresh water, and in the air and soil. Regarding water effluents, waste-water treatment plants only minimize the problem, trapping only larger size particles. In contrast, smaller ones remain in oxidation ponds or sewage sludges, or are even released to aquifers environment. Classic procedures for MPs detection are still quite laborious, and are usually conducted off-line, involving several steps and expensive equipment. Electrical Impedance Spectroscopy, EIS, is a technique that allows the analysis of a system’s electrical response, yielding helpful information about its domain-dependent on physical-chemical properties. Due to the superficial electronegativity of MPs’ particles, EIS may allow to attain the purpose of the present work: to provide a fast and reliable method to detect/estimate MPs’ concentration in water effluents. Among the most common microplastics are Polyethylene, PE, and Polyvinyl Chloride, PVC. Using the developed setup and experimental data collection methodology, the authors could differentiate between MPs’ suspensions containing the same concentration of the different evaluated MPs, PVC and PE, and assess PVC concentration variation, in the interval between 0.03 to 0.5 g (w/w), with an error, estimated based on the obtained impedance modulus, around or below 3% for the entire stimulus signal frequency range (from 100 Hz to 40 MHz) for the PVC particles.
