The College of Science, Misan University discussed a master dissertation on the synthesis and characterization of electrolytically woven polymer nanofibers. by the postgraduate student, Mr. Murtadha Shihab Ahmed

The dissertation aimed to prepare and evaluate polyacrylic acid and chitosan (PAA-Chi) nanofibers in a 30:70 weight ratio using electrospinning technology to efficiently remove methylene blue dye from aqueous solutions.

The dissertation reviewed that the prepared nanofibers possess a homogeneous, defect-free structure with an average nanodiameter of approximately 276 nm. Zeta potential analysis also showed a negative surface charge, which enhanced the electrostatic interaction with the cationic dye.

The dissertation concluded that the nanofibers exhibited a maximum adsorption efficiency (Qmax) of 78 mg/g under ideal conditions at pH 6 and 25°C. 

The dissertation confirmed that PAA-Chi composite nanofibers are a promising, highly efficient and low-cost adsorbent material for treating industrial wastewater contaminated with cationic organic dyes.
