(383ad) Enhanced Removal of Heavy Metals from Contaminated Water Using Psf Hollow Fiber Membrane Blended with Fe3O4/Mwcnts-COOH Nanohybrid

The prevalence of cadmium and arsenic in water due to mining and metal processing presents severe health risks, including nephrotoxicity, neurotoxicity, hepatotoxicity, skin issues, and cardiovascular problems. Among various removal methods like adsorption, electrochemical precipitation, activated carbon, and ion exchange, membrane separation stands out as an efficient solution. In this study, a Fe₃O₄/MWCNTs-COOH nanohybrid was integrated into Psf (polysulfone) hollow fiber membranes (HFMs) to enhance their separation efficiency for heavy metal removal.The modified HFMs demonstrated a significant five-fold increase in pure water permeability compared to unmodified membranes, along with excellent antifouling properties. Notably, the maximum adsorption capacities for Cd²⁺ and As³⁺ were observed, indicating the effectiveness of the modified membranes in heavy metal adsorption. High removal efficiencies were achieved for Cd²⁺ and As³⁺ in both lab-made and natural lake water samples. Moreover, a reusability study confirmed the modified membrane's ability to be revived and reused for up to five cycles without compromising performance.These findings highlight the significant potential of the modified membrane for efficiently removing toxic metals like Cd²⁺ and As³⁺ from aqueous solutions. The enhanced membrane's promising application in water treatment processes is evident, showcasing its role in addressing environmental and health concerns related to heavy metal contamination in water sources.
