The aim of this work is to study the degradation and mineralization of antibiotic ofloxacin in aqueous medium using the Electro-Fenton method as advanced oxidation technology. In this context, Pt/carbon-felt cell was used to investigate the influence of various parameters including initial pH, different supporting electrolytes, different metal ions as a catalyst and antibiotic concentration ove...

This work analyses the water transport and ionic losses in bipolar membranes at electrolysis cells conditions. In common setups, is split interface between anion exchange membrane (AEM) cation (CEM). Accordingly, ions (protons hydroxide ions) are transported to electrodes, carrying out of both via electro-osmotic drag. These outfluxes plus required amount for splitting process have be compensat...

To recover gold, this work used a novel direct contact membrane distillation (DCMD) reactor with a hybrid electrolytic process. Analytical results demonstrate that permeate flux increased as feed -2 -1 temperature and feed flow rate increased. Permeate flux increased from 2.8 to 17.6 kg m h when -2 -1 temperature increased from 30 to 70 °C, and increased from 9.2 to 19.9 kg m h when the feed fl...

Anaerobic digestion of waste activated sludge (WAS) is relatively poor due to hydrolysis limitations. Acid and alkaline pretreatments are effective in enhancing hydrolysis leading to higher methane yields. However, chemical costs often prohibit full-scale application. In this study, 12 V two-chamber electrolysis using an anion exchange membrane alters sludge pH without chemical dosing. pH dropp...

Electrocatalytic conversion of carbon monoxide (CO) is being actively developed as a key component for tandem CO2 electrolysis. Great effort has been devoted to engineering CO reduction electrocatalysts better multicarbon product selectivity. However, less work focused on other performance parameters that are crucial commercializing electrolysis, such liquid concentration and purity. Here, we p...

Anion exchange membrane water electrolysis technology is an environmentally friendly method for hydrogen production without carbon dioxide emissions. The development of this hindered by the sluggish rates and oxygen evolution reactions, demanding rational design electrocatalysts these processes. Although numerous are reported in literature, there currently no standard set conditions or cell und...
