Abstract: Poly (vinylidene fluoride) (PVDF)/graphene oxide (GO) ultrafiltration (UF) membranes are prepared via immersion precipitation phase inversion process. Raman spectra results indicate the existence of GO in PVDF/GO UF membranes. SEM pictures show that the PVDF/GO UF membranes present developed finger-like pore substructure along with the increased porosity and mean pore size. As revealed by FT-IR spectra, large amount of OH groups are appeared due to the introduction of GO nanosheets that improve the surface hydrophilicity of the modified membrane. In permeation experiment, the water flux is improved after blending GO. With 2 wt% GO content, the pure water flux and permeation flux reach peak values of 26.49 L/m2 h and 14.21 L/m2 h, increasing 79% and 99% respectively. Furthermore, the flux recovery ratio (FRR) and the fouling resistance results suggest that PVDF/GO UF membranes have better antifouling properties than pure PVDF due to the changes of surface hydrophilicity and membrane morphologies. AFM images show that UF membranes have a smoother surface with a higher efficient filtration area, which would enhance antifouling properties.

TL;DR: In this paper, a review of the electrochemical methods used at lab and pilot plant scale to decontaminate synthetic and real effluents containing dyes, considering the period from 2009 to 2013, as an update of our previous review up to 2008.
Abstract: As the environment preservation gradually becomes a matter of major social concern and more strict legislation is being imposed on effluent discharge, more effective processes are required to deal with non-readily biodegradable and toxic pollutants. Synthetic organic dyes in industrial effluents cannot be destroyed in conventional wastewater treatment and consequently, an urgent challenge is the development of new environmentally benign technologies able to mineralize completely these non-biodegradable compounds. This review aims to increase the knowledge on the electrochemical methods used at lab and pilot plant scale to decontaminate synthetic and real effluents containing dyes, considering the period from 2009 to 2013, as an update of our previous review up to 2008. Fundamentals and main applications of electrochemical advanced oxidation processes and the other electrochemical approaches are described. Typical methods such as electrocoagulation, electrochemical reduction, electrochemical oxidation and indirect electro-oxidation with active chlorine species are discussed. Recent advances on electrocatalysis related to the nature of anode material to generate strong heterogeneous OH as mediated oxidant of dyes in electrochemical oxidation are extensively examined. The fast destruction of dyestuffs mediated with electrogenerated active chlorine is analyzed. Electro-Fenton and photo-assisted electrochemical methods like photoelectrocatalysis and photoelectro-Fenton, which destroy dyes by heterogeneous OH and/or homogeneous OH produced in the solution bulk, are described. Current advantages of the exposition of effluents to sunlight in the emerging photo-assisted procedures of solar photoelectrocatalysis and solar photoelectro-Fenton are detailed. The characteristics of novel combined methods involving photocatalysis, adsorption, nanofiltration, microwaves and ultrasounds among others and the use of microbial fuel cells are finally discussed.
