Calcium Ion Impregnated on Water Hyacinth for Defluoridation of Water

Eichhornia Crassipes) leaf powder was used  as biomass along with the loaded calcium ion. Calcium carbonate (CaCO₃) was used as doping reagent in microwave. Batch experiments were carried out for 5-25 mg/l of fluoride concentration. It was observed that using water hyacinth loaded with the calcium ion 83.34 % fluoride removal was achieved. The effect of various parameters on fluoride removal was studied in batch experiments
