Abstract
Excess fluoride in drinking water hazarded people health, so we have undertaken to develop a nanoscale \(\hbox {FeOOH}/{\upgamma }\hbox {-Al}_{2}\hbox {O}_{3}\) absorbent to remove fluoride in drinking water. The as-prepared nanoscale \(\hbox {FeOOH}/{\upgamma }\hbox {-Al}_{2}\hbox {O}_{3}\) absorbent was characterized by transmission electron microscopy, surface area analyzer, and X-ray diffraction. Herein, we explored the effect of pH of solution, concentration of initial fluoride, contact time, and temperature on defluoride efficiency. The results showed the composite owned to further adherence to defluoride, compared to spherical and mesoporous alumina granules. The experiment data were fit with different models and assessed by regression coefficient \((R^{2})\); the pseudo-second-order model was used to explain the adsorption process. The adsorption mechanism can be explained by a proton shifting mechanism.
