Treatment of fluoride contaminated water using mango (Mangifera indica) leaves powder as an adsorbent

Excessive levels of Fluoride in water is detrimental to human health as it can cause many health problems including both dental and skeletal fluorosis etc. The aims of the current research work were to prepare a novel check the efficiency of Mango (Mangifera indica) leaves powder (MLP) for fluoride removal as well as to observe the effect of various factors over fluoride adsorption from water. The experiments were performed under batch mode and the results indicated that maximum adsorption efficiency was noticed in the acidic range. The Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FTIR) techniques were applied for adsorbent characterization. Data modeling declared that pseudo second order kinetic model and Langmuir isotherm models were in best fitting. The study concluded that the investigated adsorbent material is suitable for reducing the high fluoride concentration in water to the WHO established level and is suggested as an ecofriendly material for water purification. Conclusively, future research prospects and further modification of mango leaves materials for fluoride adsorption are recommended.
