Development and Characterization of Ternary Hybrid Membranes in Natural Polymers and their Application in the Microbiology Field

Abstract

New ternary membranes have been synthesized and characterized. The membranes have been elaborated with natural polymers such as "corn starch" and "Bentonite" added with activated carbon. The technique of phase reversal induced by a solvent at ambient temperature has been applied for the development of these membranes. A set of characterization techniques which include FTIR, SEM are used for structural, morphological knowledge. The ternary membranes are performed on microbiological separation for the filtration of bacteria (Escherichia coli, Pseudomonas aeruginosa) and fungus (Aspergillus niger, Penicillium notatium) and compared to binary membranes which include natural polymers such as "corn starch" and "Bentonite" as compositions. Results showed that the ternary membrane has high performance compared to binary membranes for the filtration Escherichia coli, Pseudomonas aeruginosa and fungi Aspergillus niger.
