Abstract
This study introduces a novel halloysite/alumina composite material for effective defluoridation, addressing the urgent need for advanced materials to treat fluoride-contaminated water. Traditional defluoridation methods often fail to meet the stringent fluoride limits set by WHO and national standards, highlighting the need for innovative solutions. This study introduces a composite using natural tubular halloysite, a low-cost and widely available mineral, with nanoporous gamma alumina, synthesized through a co-precipitation and activation method. The resulting composite demonstrated a superior Langmuir theoretical maximum adsorption capacity of 225.8 mg/g under optimal synthesis conditions of pH 8 and 600 °C calcination. Extensive structural characterization confirmed the successful integration of alumina onto halloysite. Adsorption tests indicated high efficiency across an initial pH range of 3–8 and resilience against common anionic interferences. Kinetic analysis identified active site adsorption as the predominant mechanism, while thermodynamic modeling suggested Freundlich adsorption behavior indicative of heterogeneous surfaces. This halloysite/alumina composite emerges as a high-performance, and economical fluoride adsorbent with significant potential for practical application, particularly in treating fluoride-rich industrial wastewater. The material’s effectiveness at low dosages and competitive adsorption capacity represent a significant advancement in sustainable water purification, offering both environmental and economic benefits.
