Abstract :

Fluoride due to its toxic nature can be harmful to human body if taken in excess amount. Millions of people are suffering from serious crippling bone diseases due to elevated levels of fluoride present in drinking water. The research made a novel Zr-Mn composite material with high sorption capacity for fluoride through co-precipitation method for the adsorption of fluoride from water. The adsorption was confirmed by the use of various techniques like X-ray diffraction (XRD) analysis, Fourier transform infrared (FT-IR), Brunauer, Emmett and Teller (BET). 90% fluoride removal was achieved using 1.2g/50mL of adsorbent dose and contact time 145 min at pH 7. The effectiveness of the sorption process on the adsorbent (Zr-Mn composite material) was verified by testing it on natural waters loaded with the proposed fluoride. The process comes out to be easy as well as cost effective for adsorption of fluoride, it also follows Freundlich and Langmuir isotherms of adsorption.
