“…Generally, the separation mechanism identified for removing solutes with molecular weights larger than the MWCO of the membrane is purely size exclusion. However, ceramic UF membranes have larger MWCOs than the molecular weight of the target PhACs which indicates that size exclusion is not the main separation mechanism and therefore, the electrostatic interactions between the charge of both membrane surface and PhACs play an active role in rejection of charged solutes [13]. The isoelectric point of the ceramic membranes was about 6, resulting in membranes positively charged at pH 4 and negatively charged at pH 7 and 10.…”

“…Although SUL is hydrophilic within the pH range (log KOW is between 0.5 and 0.89), both NAP and IBU have a log KOW higher than 2.6, presenting high hydrophobicity which could lead to the hydrophobic interactions (adsorption) of these compounds onto the polymeric surface of the membrane [29]. Even though the adsorption on the membrane could be significant, hydrophobic PhACs are ultimately rejected due to size exclusion mechanism [13]. Likewise, the importance of electrostatic interaction should be taken into account.…”

“…In these cases, the rejection is predominantly governed by electrostatic mechanisms, where the positively charged PhAC is attracted by the negatively charged membrane, at which the accumulation of the organic solute as a thin layer may occur. The strong interaction between this positively charged solute and the negatively charged surface of the membrane causes the dissolution and diffusion of the solute across the membrane matrix [13,30]. However, this organic solute changes its charge at pH 7 (becoming a mixture of neutral and positively charged solute) and 8…”

García-Ivars, J.; Iborra Clar, MI.; Massella, M.; Carbonell Alcaina, C.; Alcaina-Miranda, MI. (2017). Removal of pharmaceutically active compounds using low-pressure membrane processes. Desalination and Water Treatment. 69:252-260. doi:10.5004/dwt.2017 ABSTRACTThe increasing demand on water resources throughout the world has motivated researchers to seek new ways to obtain quality water increasing their interest in water reclamation. However, the presence of harmful organic chemicals such as pharmaceutically active compounds (PhACs) is a serious environmental concern. The objective of this study was to investigate the influence of the pH on the rejection of seven target PhACs (acetaminophen, caffeine, erythromycin, ibuprofen, naproxen, sulfamethoxazole, and trimethoprim) by different low-pressure membranes within the 2 fine ultrafiltration (UF) and loose nanofiltration (NF) range. For this purpose, three ceramic membranes and a polyamide membrane were used for UF and NF experiments, respectively. Experimental results indicated that PhACs with negative charge were effectively rejected at basic conditions (< 75% for UF, < 90% for NF), improving both their hydrophilicity and solubility with increasing pH. Furthermore, high soluble PhACs with high pKa values showed low rejection values (~15% for UF, ~30% for NF) and a pH-independent behaviour during low-pressure filtration experiments. Therefore, the use of low-pressure membranes could be considered as an appropriate and sustainable supplemental technique to remove PhACs in a wastewater treatment plant.

Novel antimony doped tin oxide/carbon aerogel as efficient electrocatalytic filtration membrane

et al. 2016

A facile method was developed to prepare antimony doped tin oxide (Sb-SnO2)/carbon aerogel (CA) for use as an electrocatalytic filtration membrane. The preparation process included synthesis of a precursor sol, impregnation, and thermal decomposition. The Sb-SnO2, which was tetragonal in phase with an average crystallite size of 10.8 nm, was uniformly distributed on the CA surface and firmly attached via carbon-oxygen-tin chemical bonds. Preliminary filtration tests indicated that the Sb-SnO2/CA membrane had a high rate of total organic carbon removal for aqueous tetracycline owing to its high current efficiency and electrode stability.
