“…Similar behavior was observed by (Baddouh et al 2019) for the removal of MB by AO SnO2 anodes. As for coupling AO with biosorption the variation of the effect of concentration is similar to each process alone.…”

The present paper aims to valorize the use of cheap agricultural waste materials for polluted water decontamination. An evaluation of the efficiency of coupling anodic oxidation (AO) using SS/PbO2 electrodes with biosorption by Luffa cylindrica (L.C) for the removal of Amaranth Red (E123) from aqueous solution was investigated. The effects of pH, contact time, and initial concentration were studied. The regeneration of L.C was estimated based on biosorption /desorption tests. The performance of the coupling process was evaluated based on the color, chemical organic carbon (COD), Total organic carbon (TOC) removals, the energy consumed, and the time required for the degradation of Amaranth. A comparison between the efficiency of the AO and the coupling process for the increase of the lifetimes of the anodes used was done. 54.1, 97.8, and 99.9% of 50 mg.L -1 of Amaranth were removed respectively after 85, 65, and 50 min by biosorption, AO, and coupling AO with biosorption. An increase in the percentages of COD, TOC, germination indexes (GI), and Amaranth removals were observed when adopting the coupling process. Furthermore, a decrease in the release of Pb 2+ ions was observed confirming the good stability of the elaborated anodes during the coupling process. Atomic absorption analysis showed that the Pb 2+ ions reached about 0.020 mg.L -1 , after the total removal of Amaranth dye (60 min) and 0.051 after (80 min) respectively, for coupling AO with biosorption and the AO process. These values are inferior to those allowed by the Standards. Phytotoxicity tests confirmed the possibility of the reuse of the treated solutions.

“…The electrochemical oxidation of Amaranth Red (E123) can be divided into two main stages (Baddouh et al 2019); the first one consists of the formation of hydroxyl radicals (OH • ), which is evolved at the anode (M= SS/PbO2) upon water discharge reaction (Eq. ( 10))…”

“…Here in we report the synthesis of a low cost sulphate anion based protic ionic liquid; triethylammonium sulphate (TEAS) and characterized through 1 H NMR, FT-IR and Karl-Fischer (KF) titration. Electrochemistry can be employed in many research fields and for different types of electrolytes used for different specific purposes [19][20][21][22]. The PIL was subjected also to electrochemical investigation through cyclic voltammetry to determined its EW at Au and Pt electrodes and examined the effect of temperature on the EW of TEAS.…”

Protic ionic liquids (PILs) being intrinsic proton conducting ionic species are considered as potential green electrolytes for study of electrocatalytic reactions and for fabrication of IL-based fuel cells (FCs) and batteries. We have prepared a sulfate anion based protic ionic liquid (PIL), triethylammonium sulfate (TEAS) through a reaction involving transfer of proton from H2SO4 to triethylamine (TEA). 1H NMR and FT-IR spectroscopic techniques were employed for confirmation of the synthesis of TEAS and water content of the PIL was quantified using coulometric Karl–Fischer (KF) titration. 1H NMR and FT-IR analysis confirm the synthesis of the PILs and KF-titration analysis shows that TEAS contains 1.43 w/w % water. Electrical conductivity of TEAS was determined at different temperatures showing that the PIL has excellent ionic conductivity that enhances with rise in temperature of the medium. The temperature dependence of the conductivity of the PIL follows the Arrhenius equation as the logσ versus 1/T plot is linear. The electrochemical windows (EWs) of the electrolyte were found using cyclic voltammetry at Pt and Au working electrodes and found to decrease with increase in temperature of the medium. The data revealed that the surfaces of the electrodes are covered with oxide layers due to oxidation of trace water (1.43 w/w %) present in the PIL. The oxide layers growth increase and their onset potential moves to less positive values as the temperature of the PILs is increased. The data was compared with the literature and would be helpful in understanding of the surface electrochemistry in this neoteric medium for being used as potential electrolyte in industry for various electrochemical applications.
