Recebido em 24/5/05; aceito em 16/3/06; publicado na web em 13/7/06 COMPARATIVE STUDY OF SILICA OBTAINED FROM ACID LEACHING OF RICE HUSK AND THE SILICA OBTAINED BY THERMAL TREATMENT OF RICE HUSK ASH. A comparison between silica by acid leaching of rice husk (RH) and silica obtained from thermal treatment of rice husk ash (RHA) is presented. The best leaching results were obtained using 10% hydrochloric acid followed by washing with water. The alternative method, calcination of RHA at 700 ºC for
