Rice husk collected in Barreiras City, Bahia, Brazil was converted to rice husk ash (RHA) by acidic or basic leaching, followed by calcination. The resulting RHA was modified with vanadium pentoxide (2, 5, or 10 mass% of [V.sub.2][O.sub.5]). The modified RHA samples were characterized by X-ray diffr...
