Disinfection of synthetic human urine by mixed metal oxide anode through photo/electrochemical oxidation
This study investigates the electrooxidation treatment of synthetic urine (SU) using quaternary mixed metal oxide (d-MMO) anodes in both batch and continuous modes. We combine photocatalysis (PC) and electrooxidation (EO) to enhance pollutant degradation. The impact of treatment time, pH, Na/Cl ratio, and current density on COD removal and the specific energy consumption is examined. Optimized parameters for batch EO treatment yield a desirability value (D) of 0.941, with COD removal of 90.55 % and energy consumption of 20.851 kWh/kg of COD removed. Treatment time is reduced from 10.05 h to 6.5 h with PEC (Photoelectrocatalysis) incorporation. The stability and durability of anodes are confirmed through XRD and FE-SEM/EDS analysis, even after 500 recycling cycles. This research stands out for utilizing innovative d-MMO anodes for EO and PEC, capturing molecular hydrogen gas during scale-up trials for SU. Through this study, we are proposing for the first time, the novel composition of d-MMO (Ti/IrO2/Ta2O5/SnO2/Sb2O5) for the treatment of SU on a pilot-scale in continuous mode with solar panels, thus making the process cost effective with less energy consumption.
期刊介绍：
Environmental Nanotechnology, Monitoring and Management is a journal devoted to the publication of peer reviewed original research on environmental nanotechnologies, monitoring studies and management for water, soil , waste and human health samples. Critical review articles, short communications and scientific policy briefs are also welcome. The journal will include all environmental matrices except air. Nanomaterials were suggested as efficient cost-effective and environmental friendly alternative to existing treatment materials, from the standpoints of both resource conservation and environmental remediation. The journal aims to receive papers in the field of nanotechnology covering; Developments of new nanosorbents for: •Groundwater, drinking water and wastewater treatment •Remediation of contaminated sites •Assessment of novel nanotechnologies including sustainability and life cycle implications Monitoring and Management papers should cover the fields of: •Novel analytical methods applied to environmental and health samples •Fate and transport of pollutants in the environment •Case studies covering environmental monitoring and public health •Water and soil prevention and legislation •Industrial and hazardous waste- legislation, characterisation, management practices, minimization, treatment and disposal •Environmental management and remediation
