چکیده
The present work reports the development and application of gas diffusion electrode (GDE) based on carbon Printex L6 modified with 5% Co-Porphyrin/CPL6 for removal Bisphenol S (BPS) in wastewater using different electrochemical advanced oxidation processes (EAOPs). GDE led to in-situ generation 333 mg L?1 H2O2 only 90 min; this represents an increase 88% relation unmodified GDE. process involving bisphenol degradation fitted well into a pseudo-first order kinetic reaction all treatment techniques evaluated; investigated recorded rate constant following order: anodic (0.004 min?1) < UV-C (0.006 (0.008 H2O2/UV-C (0.016 electro-Fenton (0.063 photo (0.154 min?1). (PEF) exhibited best efficiency; BPS was completely removed after 30 min 78% mineralization 360 treatment. remaining organic matter under PEF corresponded short-chain carboxylic acids; confirms efficiency applied decontamination. results obtained show that proposed mechanism can be successfully combined cheaper biological treatments total remediation wastes.

In this paper, the effect of surface area of reaction layers in gas diffusion electrodes on oxygen reduction reaction was investigated. For this purpose, various amounts (0.1, 0.2, 0.3, 0.4, 0.5, 1, 1.5 and zero %wt of total loading of reaction layer) of single walled carbon nanotube (SWCNT) were inserted in the reaction layer. The performance of gas diffusion electrodes for oxygen reduction re...

The main focus of this study is improvement of the steam-methane reforming (SMR) process by in-situ CO2 removal to produce high hydrogen content synthesis gas. Sorption-enhanced (SE) concept is applied to improve process performance. In the proposed structure, the solid phase CO2 adsorbents and pre-reformed gas stream are introduced to a gas-flowing solids-fixed bed reactor (GFSFBR). One dimens...
