Abstract
During the last few decades, freshwater resources were remarkably diminished in several areas of the world. This problem can be expected to aggravate as a result of multiple factors such as population growth, water contamination, climate change, and abuse of water resources, leading to a freshwater scarcity problem The World Water Council (WWC) predicts that, by the end of 2030, 3.9 billion people will strongly suffer from water scarcity, around the world. Therefore, water scarcity is a dormant crisis about to burst worldwide. Consequently, there is an urgent need for developing simple, efficient, and feasible technologies for wastewater remediation.
Membrane technologies are preferred over many other technologies for water remediation owing to their unmatched features including economic, selective, mild operating conditions, efficiency, no need for chemical or thermal treatments, reliable purification, and eco-friendship. In the last few decades, membrane technology has developed with the integration of filtration and adsorption processes. Membrane-coated adsorbents were effectively applied in water desalination and removal of hazardous pollutants including heavy metal ions, anions, toxic organic compounds, and dyes from wastewater.
This study aimed to design a facile and efficient protocol to synthesize synthesized poly(ionic) chitosan Schiff bases (PICSBs) and poly(ionic) crosslinked chitosan Schiff bases (PICCSBs) which will be used as additives for upgrading the performance indices of polysulfone (PS) membrane (porosity, hydrophilicity, pure water flux (PWF), surface charge, and fouling-resistance) and consequently its efficiency to remove pollutants for fertilizer industry`s effluents.
