The photocatalyst was prepared by immobilization of Fe3+ into the molecular sieve (4A type) surface and characterized by x-ray difractometry and UV-Vis, infrared, Mosbauer and EPR spectroscopy, TG and FAAS. The solid containing 0,85% (w/w) of ferric ions was used in degradation studies of aqueous reactive-dyes samples with really promissory results. Generally, UV-A-assisted photochemical processes leads to almost total decolorization of all tested dyes at reaction times lower than 30 min.", publisher = {UNICENTRO - Universidade Estadual do Centro Oeste}, scholl = {Programa de Pós-Graduação em Química (Mestrado)}, note = {Unicentro::Departamento de Ciências Exatas e de Tecnologia} }
