Abstract:
An alumina-based adsorbent and method of making exhibiting high affinity and capacity towards fluoride ions and oxyanions of phosphorus and arsenic in a broad pH range and presence of large excess of competitive ions. Alumina based adsorbent is a mixed oxide of alumina existing in tetra-, penta-, and octahedral coordination at specific ratio, and oxides of polyvalent metals of elements titanium, zirconium, tin, cerium, lanthanum, iron, or combinations thereof. The alumina based adsorbent may be used for selective removal of fluoride ion and oxyanions of phosphorus and arsenic from drinking water, industrial streams and wastes, in medicine and food industry.

Claim (Index 21):
The method of  claim 16  wherein said adsorbent includes combining 147 g of Al(NO 3 )3*9H 2 O, 10 g of anatase TiO 2 , and 400 g of deionized water, with NaOH at 25 wt % solution and water at said pH level of precipitation from about 4 to about 10, such that said adsorbent, when dried, contains a ratio of Al 2 O 3  and TiO 2 .
