摘要
pOrganic-inorganic composite material based on metal oxide and carbon, nitrogen and other elements/functional groups for removal of anionic pollutants like arsenic, fluoride etc., from water, and methods for making the same are disclosed. The modified composition may comprise different phases of metal oxides, supported or promoted by incorporation of nitrogen, carbon and other elements/groups. The organic-inorganic composite may be produced from at least one biogenic material such as chitin, chitosan, leaf, bio-membrane and a salt of metal like iron, aluminium etc. The organic-inorganic composite based adsorbent shows arsenic uptake capacity in the range of 0.2 to 1.3 mg/g and fluoride uptake capacity in the range of 5-50 mg/g under different conditions, which is substantially high from the other adsorbents known so far. A breakthrough regeneration of 98-99% has been achieved by using new regeneration protocol./p[WO2012077033A2]
