“…In the last years, plasma-liquid systems have attracted considerable attention of researchers on a variety of applications domains that include, i.e., environmental and wastewater remediation [7,8], nanomaterial processing [9,10], cancer cells treatment [11], sterilization and disinfection [12], bacterial biofilm prevention and eradication [13] and analytical chemistry [14,15] … etc. In particular, plasma treatment techniques have been tested: i) for the decomposition of many harmful compounds from water, including; herbicide [16], pesticides [17], phenols [7,18], organic dyes [19], As 3+ , Cr 6+ , Fe 3+ , Cu 2+ and Zn 2+ [20,21], biomolecules, Virus and bacterial Inactivation [22][23][24][25], pharmaceuticals [26,4] and veterinary antibiotics [27]; ii) For the possible removing of chemical and biological wastes in all three states; gas, liquid and solid [28]; for the enhancement of biodegradability of coking wastewater [29].…”
