Abstract

A PRESENTE INVENÇÃO REFERE-SE A UM POLÍMERO NANOCOMPÓSITO HÍBRIDO COMPOSTO POR UMA PARTE ORGÂNICA E OUTRA INORGÂNICA, PARA A REMEDIAÇÃO DE MEIOS AQUÁTICOS CONTAMINADOS COM ANIÕES COMOFOSFATOS, NITRATOS, SULFATOS E POLIFOSTATOS. O NANOCOMPÓSITO, POR SER COMPOSTO POR POLIPROPILENO ENXERTADO COM ANIDRIDO MALEICO E ISOPROPOXIDO DE ALUMÍNIO, CRIA FORTES LIGAÇÕES COVALENTES OU IÓNICAS ENTRE O COMPONENTE ORGÂNICO E O INORGÂNICO, O QUE LHE CONFERE ELEVADA RESISTÊNCIA MECÂNICA ASSOCIADA À IMPOSSIBILIDADE DE DISSOLUÇÂO DOS SEUS COMPONENTES NO CORPO AQUÁTICO. O NANOCOMPÓSITO HÍBRIDO PODE SER APLICADO IN SITU, ATRAVÉS DA CONSTRUÇÃO DE UMA BARREIRA REATIVA PERMEÁVEL INSERIDA NO MEIO AQUÁTICO QUE É ATRAVESSADA PELA ÁGUA A TRATAR, OU EX SITU, SENDONECESSÁRIO PARA O EFEITO BOMBEAR A ÁGUA A TRATAR, FAZÊ-LA ATRAVESSAR UM FILTRO CONTENDO O NANOCOMPÓSITO HÍBRIDO E FINALMENTE DEVOLVÊ-LA AO MEIO AQUÁTICO, PODENDO SER MOLDADO DEACORDO COM O TIPO DE APLICAÇÂO E O LOCAL EM CAUSA. VÁRIAS TÉCNICAS DE CARACTERIZAÇÂO COMO MÉTODOS EXPETRAIS E AVALIAÇÂO DAS PROPRIEDADES REOLÓGÍCAS, DO PONTO DE CARGA ZERO E CINÉTICA DE REMOÇÃO DO IÁO FOSFATO, DEMONSTRAM QUE O PRODUTO NÃO ALTERA O PH NEM CONTAMINA A PRÓPRIA ÁGUA.
