In this work three differente aluminosilicates were used for evaluation of the index of recovery of the coloring monovalent metilene blue. The no-porous clay mineral, Kaolinite, from Capim river area in Pará, Brazil, was treated with hydrochloric acid 5N in order to increase the specific area. The microporous molecular sieve, zeolite NaP, was synthesized through the hidrotermal method, with the kaolinite of Capim river area being used as source of Si and Al. The hidrotermal method was also used for the synthesis of the mesoporous molecular sieve Al-MCM-48, wich received thermal treatment (calcination) at 540ºC under flow of N2 and air for 7h to removal of the agent director (surfactant). The porous and no-porous materials were characterized...
