Iron Oxide Nanoparticles Derived from Mill Scale Waste as Potential Scavenging Agent in Dye Wastewater Treatment for Batik Industry

Abstract

In this work, iron oxide were derived from millscale has been used as a potential scavenging agent in wastewater treatment due to its high adsorption capacity and its shorter sedimentation time during wastewater treatment. Iron oxide obtained from the magnetic separation technique was subjected to high energy ball milling (HEBM) at different milling time to produce different size of nanoparticles of iron oxide. X-ray diffraction (XRD), Field Emission Scanning Electron Microscope (FESEM) and Scanning Trasmission Electron microscopy (STEM) were performed to study the morphological properties of the iron oxide nanoparticles. After HEBM, iron oxide nanoparticles was modified with Hexadecyltrimethylammonium Bromide (CTAB) to study the adsorption possibility of iron oxide nanoparticle modified with CTAB (Iron oxide– CTAB nanoparticles) in dye wastewater. The variation effect of particle size of derived Iron oxide– CTAB were studied. Permanent magnet was used to separate iron oxide nanoparticles from the solution. The clear part of the solution (treated wastewater) was filtered out and adsorption efficiency of Iron oxide– CTAB nanoparticles was measured using UV – Visible spectroscopy. Efficiency adsorption of iron oxide nanoparticles modified with CTAB greatly achieved above 99 % and the size of iron oxide nanoparticles affected its performance in dye wastewater treatment.

Waste-Derived Nanoparticles: Synthesis Approaches, Environmental Applications, and Sustainability Considerations

“…Several research groups are attempting to find novel nanotechnology-enabled treatments for industrial wastewater using recycled nanoparticles, which helps meet circularity and sustainability goals. Arifin et al (2017) developed iron oxide nanoparticles from mill scale and applied them to dye removal. In their process, iron oxide particles were removed from the unwanted components of mill scaling using magnetic separation techniques.…”

“…The particles were then processed using conventional and high energy ball milling and treated with hexadecyltrimethylammonium bromide to prevent aggregation. In dye wastewater, the adsorption by the modified iron nanoparticles was above 99% with optimum adsorption of 99.93% with 53.76 nm particles (Arifin et al, 2017). Giri et al 2011developed a method for creating magnetite (Fe 3 O 4 ) nanoparticles from iron ore tailings.…”
