Abstract |
The development of membranes intended for the ultrafiltration of wastewater-models loaded with vat dyes, the case of indigo, has taken during this work a major interest. This development was based on the synthesis of films, by phase inversion, permselective based on organic polymers such as polysulfone (PSU), polyvinyl chloride (PVC) and expanded polystyrene (PSE) on the one hand and based on octaglycidylether tetraaniline resin for methylenedianiline (OGTAPMDA), bisphenol A (BA) and titanium dioxide TiO2, on the other hand. During the first step, we synthesized five types of membranes named M1, M2, M3, M4 and M5 according to different percentages of the composition of the collodium (polymer/solvent/non-solvent) obtained namely; M1 (12 % PSU/88 % DMF), M2 (9 % PSU/ 1% PVC/ 90% DMF), M3 (13.5 % PSU/0.5 % BA/1 % PSe/85 % DMF), M4 (8.5 % PSU/1.5 % OGTAPMDA/90 % DMF) and M5 (9.5 % PSU/0.5 % TiO2/90 % DMF). The resulting membranes have already been characterized by researchers from the ECOP team, using microscopic tools such as FTIR and SEM, and macroscopic tools, based on hydrodynamic conditions, namely permeability and selectivity. The results obtained during this study show that the membranes obtained having excellent mechanical and static properties, on the one hand, and the ultrafiltration of the rejection-model, on the other hand, gave significant percentages on the rate scale. Fading and which are obtained as follows; 80.36 % for the M1 membrane, 89 % for the M2 membrane, 87.24 % for the M3 membrane, 64.79 % for the M4 membrane and 86 % for the M5 membrane. |
