Novel grafting method efficiently decreases irreversible fouling of ceramic nanofiltration membranes

摘要: Availability of clean water is a growing world-wide challenge. Membrane filtration considered to be very powerful technology tackle this problem. While membranes have enjoyed increasing popularity, the has an inherent Achilles heel: fouling. Despite being frequently studied, fouling remains poorly understood and incompletely resolved. The most sustainable way mitigate prevention undesired adsorption by nano-engineering membrane surface. In study, commercially available TiO2 NF were modified applying both Phosphonic acids Grignard grafting techniques. Hydrophilicity, pore size, structural changes after investigated measuring contact angles, molecular weight cut-off values, permeabilities. Model foulants mimicking in surface treatment for drinking production, one difficult situations, used. From obtained results, it was concluded that mentioned techniques definitely decreases their tendency. Correlation foulant chemistries variety graftings provided understanding process at nanoscale, underlined importance unique bond created grafting. These ground-breaking insights allowed us steer further anti-fouling strategies, are valuable other affinity-based separation processes.
