The present research work highlights preparation and application of MurrayakoenigiiL leave biomass as an alternative biosorbent for the removal of fluoride from synthetic solutions as well as real field water samples. Batch response surface methodology experiments were performed to examine the efficiency of this biosorbent. The optimum conditions for Murrayakoenigii L for maximum removal of fluoride foundto be pH=6.5, biosorbent dose of 100 mg, contact time 75 minutes and initial fluoride ion concentration 4mg/L. Before and after experiment Murrayakoenigii L leave biosorbent was examined for its morphological and functional groups present on the surface by using Scanning Electron Microscope (SEM) and FourierTransform infra red spectroscopy (FTIR) respectively. The SEM and FTIR data reveals the suitable surface and the presence of chemical functional groups such as hydroxyl, amide, carbonyl acid and primary amineon the biosorbent surface contributes to biosorption. Langmuir and Freundlich isothermal models appliedto know the type of sorption. These findings revealed that Murrayakoenigii L leave biomass can be used asan effective, low-cost, eco friendly biosorbent for the removal of fluoride from aqueous solutions as well as real field water samples.
