Commercial polyethersulfone membranes were modified to hydrophilize the surface and improve their transport properties for the nitrite removal process. The nitrites removal method from aqueous solutions is based on their ability to form complex due to binding with amino groups of the water-soluble polymer polyethyleneimine (PEI) in an acidic medium. The complex was separated using the modified membrane in the process of enhanced ultrafiltration. The surface of polyethersulfone membranes was modified using dopamine and polyacrylic acid in order to obtain a charged membrane surface, increase the water permeability coefficient, and improve transport properties. Modification conditions were established as the concentration of dopamine solution 10 mg/ml, pH = 8, T = 298 K, duration of modification 20 h, concentration of polyacrylic acid 0.5 wt.%, T = 298 K, duration of modification 2 h in the presence of EDAC. The effectiveness of the modification, the presence of new functional groups, and the change in surface morphology as a result of the modification were confirmed by infrared spectroscopy, scanning electron microscopy, and atomic force microscopy. The changes in the zeta potential of the membrane surface before and after modification were evaluated. The modification of the membranes leads to an increase in the mass transfer coefficient by 1.65 times and the water permeability coefficient by 1.2 times. The effect of pH, PEI concentration, and the presence of chlorides and sulfates on the process of nitrite extraction from solutions during ultrafiltration was studied. The optimal conditions for nitrite binding were determined as a pH value of 4; 0.5 wt.% concentration of PEI; and reaction time of 60 min. The ultrafiltration experiments of unmodified and modified PES020 commercial membranes were carried out. The productivity of modified membranes is higher than unmodified ones by 20–60 %, which compensates for a slight decrease in the retention coefficient in the process of nitrite removal. The retention coefficient of nitrites by this method is at least 70 %, which allows the effective use of this hybrid technology to remove nitrites from water in high concentrations.
