Ecofriendly Maghemite/Halloysite-like Nanotubes Nanocomposite for Highly Efficient Removal of Cd(II) from Industrial Wastewater

Abstract Kaolinite is a widely available and inexpensive substance that has been successfully employed to decontaminate different hazardous contaminants from wastewater by adsorption. In this study, halloysite-like nanotubes (HNTs) were prepared via intercalation followed ultrasonic rolling of the kaolinite layers. Then, maghemite nanoparticles co-precipitated within HNTs matrix produce maghemite/HNTs nanocomposite (MG@HNTs). XRD, SEM, TEM, FTIR, BET analyzer used characterize MG@HNTs nanocomposite, which was then utilized eliminate Cd(II) aqueous solutions (water wastewater). Using batch methodology, impact various adsorption parameters on removal explored. exhibited high capacity ( q e ) 264.47 mg g −1 for Cd (II). The kinetic data well conformed pseudo-2nd-order, while isotherms Langmuir model. desorption study demonstrated could be regenerated recycled five times, without losing its original efficiency. Furthermore, effective implementation remove cadmium real water samples, including tap industrial wastewater. This confirmed successful application as an efficient, eco-friendly, sustainable adsorbent at level feasibility uptake
