Removal of Phosphate from Water by Alumina Prepared from Sodium Aluminate
Keywords:Sodium aluminate, potassium phosphate, adsorption.
A sample of sodium aluminate was prepared from aluminum waste by the reaction with sodium hydroxide. From sodium aluminate, aluminum hydroxide was precipitated by formalin solution. The prepared aluminum hydroxide was characterized using DTA , TGA and XRD. Aluminum oxide was obtained by heating aluminum hydroxide from which adsorbent was obtained and used for removal of phosphate from wastewater. The mechanism of adsorption was discussed.
