PSf Membrane-Impregnated Jute-Copper Nanocomposite as Highly Efficient Dye Removal Material

Area of Science:

• Materials Science
• Environmental Engineering
• Nanotechnology

Background:

• Industrial dye discharge, particularly methylene blue, causes significant global water pollution.
• Conventional wastewater treatments are often inefficient for removing persistent and toxic dyes.
• There is a need for advanced materials to address water contamination challenges.

Purpose of the Study:

• To develop and evaluate a novel polysulfone-based composite membrane for methylene blue removal.
• To investigate the role of pretreated jute fibers and copper nanoparticles in dye adsorption and antimicrobial activity.
• To assess the performance and feasibility of the composite membrane for practical wastewater treatment applications.

Main Methods:

• Fabrication of a polysulfone-based composite membrane incorporating alkali and hydrogen peroxide treated jute fibers and copper nanoparticles.
• Characterization of membrane properties using FTIR, XRD, DLS, and SEM.
• Batch adsorption and desorption studies to evaluate methylene blue removal efficiency and dye retention capacity.

Main Results:

• The composite membrane exhibited superior methylene blue removal compared to individual components.
• Achieved approximately 97% removal at low methylene blue concentrations (∼20 ppm) and 85% at higher concentrations (∼100 ppm).
• Desorption studies indicated good dye retention, suggesting reusability and practical applicability.

Conclusions:

• The developed nanocomposite-fiber membrane is a highly effective and sustainable solution for removing methylene blue from aqueous solutions.
• This innovative material holds significant potential for advancing wastewater treatment technologies and promoting environmental sustainability.
• The integration of nanotechnology and natural fibers offers a cost-effective approach to mitigating water pollution.
