Resumo

O rápido desenvolvimento industrial e agrícola tem favorecido o aumento desenfreadono número de poluentes liberados no meio ambiente, principalmente, de metais tóxicosem água. Como consequência, faz-se necessário o desenvolvimento de novas tecnologiasde baixo custo, reprodutíveis e efiazes para a remoção desses contaminantes. Dentreessas tecnologias, a utilização de nanoadsorventes de óxidos metálicos vem recebendodestaque. Assim, o presente trabalho visa sintetizar o CaMoO4 utilizando radiação pormicro-ondas, caracterizar estruturalmente, morfologicamente e estudar o potencial deadsorção para íons Cd (II) e Mn (II). Observa-se que em pH 9, o material sintetizadoapresenta excelente potencial adsortivo para os íons cádmio (95%) e manganês (85%).
