WITHDRAWN: Seawater Desalination Using Microbial Desalination Cell Based on Bio-Catalytic Devices Modification.

Abstract

Abstract Microbial desalination cell (MDC) built on bio-catalytic devices modification has been studied for sea water desalination using Saccharomyces cerevisiae as biocatalyst. Here we focussed the modification of anode and this study has been confirmed that bio-catalytic devices maintenance could contribute to the long-term MDC perform during desalination process. The goal of this study is to provide and develop a sea water desalination system without requiring an energy support by applying modification of anode as electron acceptor, and the different potential charges that occur between anode and cathode can plays as driving force for electro dialysis of sea water desalination. Several types of bio-catalytic devices modification have been conducted, i.e. by immobilization of mediator, immobilization of biocatalyst or a combination of both. The optimization of each device has been characterized by cyclic voltammetry, Chronoamperometry, and applied in Microbial fuel cell prior observed in MDC. The concentrations of ion salt migration have been determined by Ion Exchange Chromatography. The profiles of surface device have been detected by Scanning electron microscope and Energy Dispersive X-ray spectroscopy. Results shows that the modification of anode could be a promising method for bioelectricity generation delivered from MDC which as simultaneously produce an electricity and sea water desalination and provide a green chemistry technology.
