Transforming an end-of-life reverse osmosis membrane in a cationic exchange membrane and its application in a fungal microbial fuel cell

This article describes for the first time elaboration of a cationic exchange membrane (CEM) from an end-of-life reverse osmosis (RO) membrane. The has been prepared in two successive steps: (i) chlorine attack and (ii) filtration/adsorption polystyrene sulfonic acid (PSS) electrolyte solution. Physicochemical characterizations have undertaken including (Na+) transference number (t(Na+)), diffusion flux measurements (Js), capacity (CEC) determinations, as properties encountered classical hydraulic permeability (Lp) was also determined to characterize molecular weight cut-off. novel denoted ANIMAX characterized by ATR-FTIR SEM/AFM tools. We utilized old brackish water BW30 (stocked bisulfite 1% 10 years) develop new sulfonated UF with cut-off 55 kDa. observed that roughness divided 2 (295 144nm) showing lower propensity fouling/biofouling elaborated. As application, newly synthesized tested during 4 days experiments fungal microbial fuel cell laboratory set-up vs Nafion© 117 usual MFC technology. external resistance value 8 kOhm 37 Nafion®117, respectively.
