Using the impregnation approach, molybdovanado phosphoric acid (MVPA) has been immobilized onto kaolin resulting in a green heterogeneous catalyst (MVPA@Kaolin). A comprehensive physicochemical analysis was performed on the catalyst. Because of its uses in fine chemicals and medicines, this hybrid material is meant to be used as a sustainable catalyst. To investigate the catalyst, a variety of physicochemical characterization approaches were used. Through the adsorption of fluoride, the performance of the material was evaluated with temperature, pH, catalyst load, and contact time. The results demonstrated rapid and efficient fluoride removal, with a removal efficiency of more than 85 % in a little contact time. The optimum pH obtained as 1 with fluoride removal efficiency of 84 %, catalyst load 5 g/L (85 %), and temperature 50 oC (85 %). Additionally, composite material regeneration and reusability were investigated. The results aid in the creation of effective and environmentally sustainable fluoride-in water treatments.
