Investigation of cobalt(II) retention from aqueous solutions by a polyamide nanofiltration membrane
Original language description
This study investigates the performance of a polyamide nanofiltration membrane (AFC 40) in the retention of Co(II) ions from aqueous solutions, their separation mechanism under various process conditions and the correlation with the membrane characteristics. The membrane performance is interpreted by analyzing the metal ion rejection and the permeate flux, as well as the proton rejection that completes the metal rejection and membrane characterization data. The results show that the membrane has a highpermeability and exhibits an amphoteric behaviour in Co(NO3)(2) solutions, and the membrane charge increases On increasing the solution concentration because of the adsorption of cobalt ions. The metal ion rejection increases when increasing the feed concentration in the range 15-1000 mg Co/L and also by increasing the transmembrane pressure. The optimum operating pressure range is 20-25 bar as the rejection reaches maximum values. The flux and rejection are significantly enhanced by dec
