"Antimicrobial Resistance: An Emerging Public Health Threat on One Health Perspectives"

Abstract

The research on clean water production is of critical importance worldwide. Excess fluoride pollutant has direct correlation with bones deformation. Bio-filters are of multilateral advantages. This study is focused on the physical treatment to prepare lowcost biochar adsorbents made from cow bone. The produced bio-filter was tested for fluoride removal from aqueous solutions containing control amounts of fluoride. The bone sample was calcined at 400 °C. Scanning electron microscopy, energy dispersive X-ray analysis, and ionic chromatography were performed to characterize the filtration performance of the charcoal adsorbent. The adsorption effectiveness of fluoride was estimated at 94%. The proposed charcoal bio-filter is economically and environmental advantageous, given its lack of energy consumption. It also provides health benefits. Furthermore, the overall performance of this bio-filter could be enhanced in the future by using nanocomposites.
