Removal of fluoride ions in drinking water using Fe2O3-zno nanocomposite emedded with grass fibre

Abstract

About 80% of the diseases in the world are due to poor quality of drinking water, and the fluoride contamination in drinking water is responsible for 65% of endemic fluorosis in the world. Fluoride deficiency may cause dental caries and excessive use of its standard may cause dental disease, liver and skeletal fluorosis. In this present study, developing a Fe₂O₃-ZnO embedded AcorusCalamus (Sambu Grass) fibre catalyst to remove excess fluoride from Devipattinam drinking water. Using catalyst such as ZnO and Fe₂O₃nanopowders which are mixed with pulverized raw grass powder. These carbon nanofibres were characterized by XRD and SEM. The derived nanocomposites were utilized for the removal of fluoride from the drinking water. The water sample was collected from Devipattinam and it was used for further analysis. The solution isotherm and kinetics experiments were performed by batch adsorption experiments and were carried out. The defluoridation studies were conducted for the optimization of various experimental conditions like contact time, initial fluoride concentration, adsorbent dose, and fluoride uptake with fixed dosage by varying pH. The percentage of fluoride ion adsorption increases with increase in adsorbent dose.At a pH of 10 which gives the maximum fluoride adsorbent for metal oxide based fiber.
