“…Because of their toxicity, accumulation in the food chain, and presence in nature, heavy metals in water pose a serious hazard to both people and animals . There is a severe drinking water scarcity, with about 42% of the global population without access to clean and safe drinking water . In many developing nations, groundwater is used for residential purposes, mostly in rural areas.…”

“… 1 There is a severe drinking water scarcity, with about 42% of the global population without access to clean and safe drinking water. 2 In many developing nations, groundwater is used for residential purposes, mostly in rural areas. However, depending on the geographical location, groundwater contains significant concentrations of minerals such as fluoride ions, making it dangerous to drink.…”

In the present work, an extract of Salvia officinalis leaves was used to synthesize an alumina/NiO nanocomposite by the coprecipitation method. First, the shape and surface content of the synthesized adsorbent were determined. Scanning electron microscopy images showed the production of nanospheres and nanorods with sizes between 35 and 50 nm. X-ray diffraction measurement revealed strong, high-intensity peaks, confirming the preparation of a highly crystalline alumina/nickel oxide nanocomposite. Then, the pure nanoalumina, nickel oxide, and functionalized alumina/nickel oxide nanocomposite for water defluoridation were investigated under various conditions, for example, stirring period, pH, and initial fluoride concentration. Defluoridation with greener alumina, nickel oxide, and alumina/nickel oxide nanocomposite lasted 120 min at adsorbent dosages of 0.8 g/L in a pH 7 solution. The adoption process for the three sorbents matches the Langmuir adsorption isotherm. The process dynamics were explored using pseudo-second-order and first-order kinetics. The water quality after treatment met drinking water requirements, proving the viability of using nanoparticles for drinking water defluoridation. This work confirmed effective water defluoridation in the crystalline phase using synthesized nanoalumina, nickel oxide, and their nanocomposite, which highlights their importance for future drinking water defluoridation.
