Abstract
Micropollutants (MPs) such as pharmaceuticals, personal care products and suspended particles have been a great menace to water resources in recent times. Especially diclofenac (DCF) and ciprofloxacin (CFP) have been shown to have varying toxic effects on several aquatic organisms. As a results, it is necessary to remove the MPs from aquatic systems. The development of membranes with enhanced permeability, fouling resistance, stability, and efficacious contaminants, as well as salt removal from wastewater. These requirements for the effective filtration of wastewater could be resolved by incorporating highly water-stable metal-organic frameworks (MOFs) into membranes. In this study, cellulose acetate (CLA), polysulfone (PS) [CLA/PS] (M1) and MOF-incorporated CLA/PS/MIL-88A membrane (M2)—were synthesized, characterised and assessed for their filtration and rejection functions. The M2 membranes exhibited high rejection efficiency of 80 % and 78 % for diclofenac and ciprofloxacin, respectively. Also, the prepared materials were characterised using suitable analytical instruments. Additionally, the membrane's antifouling properties of about 90 % flux recovery ratio and pure water permeability (84.2 L/h m2) were studied. Moreover, the MIL-88A incorporated into cellulose acetate enhances the stability and reusability of the M2 membrane, providing good potential for the stable and effective removal of micropollutants for water treatment.

Groundwater for Sustainable Development is directed to different stakeholders and professionals, including government and non-governmental organizations, international funding agencies, universities, public water institutions, public health and other public/private sector professionals, and other relevant institutions. It is aimed at professionals, academics and students in the fields of disciplines such as: groundwater and its connection to surface hydrology and environment, soil sciences, engineering, ecology, microbiology, atmospheric sciences, analytical chemistry, hydro-engineering, water technology, environmental ethics, economics, public health, policy, as well as social sciences, legal disciplines, or any other area connected with water issues. The objectives of this journal are to facilitate: • The improvement of effective and sustainable management of water resources across the globe. • The improvement of human access to groundwater resources in adequate quantity and good quality. • The meeting of the increasing demand for drinking and irrigation water needed for food security to contribute to a social and economically sound human development. • The creation of a global inter- and multidisciplinary platform and forum to improve our understanding of groundwater resources and to advocate their effective and sustainable management and protection against contamination. • Interdisciplinary information exchange and to stimulate scientific research in the fields of groundwater related sciences and social and health sciences required to achieve the United Nations Millennium Development Goals for sustainable development.
