Two types of MOF (ZIF-8 and ZIF-L) were grown within a porous £\-alumina support to form a membrane for the adsorption of a dye molecule, rose bengal, in aqueous phase. The external surface of ZIF-L was shown to exhibit strong affinity for rose bengal. We also observed that small crystals (with a large external surface area) are beneficial to adsorption. The surfactant CTAB was used in the synthesis of ZIF-L-based membrane adsorbers in order to reduce the size of ZIF-L particles and increase the loading of ZIF-L within the membrane. The membrane adsorber synthesized with the highest concentration of CTAB achieved the highest dynamic adsorption capacity. The ZIF-L-based membrane adsorbers exhibited water permeance (approximately 2 ¡Ñ 104 L m-2 bar-1 h-1) far exceeding that of most existing membrane adsorbers. ? 2017 The Royal Society of Chemistry.journal article10.1039/c7en00639j2-s2.0-85033576689https://www.scopus.com/inward/record.uri?eid=2-s2.0-85033576689&doi=10.1039%2fc7en00639j&partnerID=40&md5=372791b71755a308cc2933e552eccf3f
