Sustainable Water Purification: Iron Filings For Dye Adsorption, Saddam Alaskary

Chemical Engineering

This research explores the potential of iron filings as a sustainable adsorbent for the removal of synthetic dyes from wastewater, with a focus on Methyl Orange and Methylene Blue, two dyes commonly used in industrial processes. The iron filings were comprehensively characterized through chemical analysis, mineralogical assessment, particle size distribution, scanning electron microscopy (SEM), and Fourier transform infrared (FTIR) spectroscopy to evaluate their adsorption properties. The effects of key operational parameters—including adsorbent dosage, initial dye concentration, and contact time—on removal efficiency were systematically investigated, with experimental data analyzed using Design Expert software. Findings show that iron filings exhibit high adsorption …
