dc.description.abstract | Building on the excellent results of extraction on a solid phase (polymer) this work combine adsorption nitrophenols (a, m, p-nitrophenols) on polymeric nanoparticles (NP-PSf) and composite (NP-PSf-PANI) with colloidal ultrafiltration. Colloidal ultrafiltration solutions of nitrophenols is done in an ultrafiltration plant, CELF System, with a capacity of 500 mL at 25oC, variable working pressure (1-10 atmospheres), turbulent flow regime (2-4 m/s) and usable filter polysulfone-membrane composites 10% in dimethylformamide coagulated with methanol polyaniline (PANI-PSf) 15 cm2. Operational parameters of the process: concentration nitrophenols, nanoparticle concentration, pH of the feed solution were studied, trying to correlate the results of the colloidal ultrafiltration with the nature of the nanoparticles. Permeate flow is optimal at a pressure of 5 atm and nitrophenols retention depends on their nature. Good results have been obtained at pH = 3.1 for polysulfone nanoparticles (NP) and excellent retention at pH 1.3 or pH>7, for composite nanoparticles (NP-PSf-PANI). Rejection o-nitrophenols is superior to the others two nitrophenols in all experiments | en_US |
