This study investigates the nanofiltration process of low molecular weight organic compounds in aqueous solution, focusing on the effect of amino group position on retention. The research also observes poor separation efficiency of oxidation products of certain pharmaceuticals on commercial membranes, and suggests that pre-ozonation can improve pollutant removal.
The research covered the process of nanofiltration of low molecular weight organic compounds in aqueous solution. The article presents the results of experiments on membrane filtration of compounds containing amino groups in the aromatic ring and comparing them with the results for compounds without amino groups. The research was carried out for several commercial polymer membranes: HL, TS40, TS80, DL from various manufacturers. It has been shown that the presence of the amino group and its position in relation to the carboxyl group in the molecule affects the retention in the nanofiltration process. The research also included the oxidation products of selected pharmaceuticals. It has been shown that 4-Amino-3,5-dichlorophenol-a oxidation product of diclofenac and 4-ethylbenzaldehyde-a oxidation product of IBU, show poor separation efficiency on the selected commercial membranes, regardless of the pH value and the presence of natural organic matter (NOM). It has been shown that pre-ozonation of natural river water can improve the retention of pollutants removed.
