Abstract

MéTODO PARA FILTRAR áGUA CONTAMINADA, SISTEMA DE FILTRAçãO DE áGUA, E, MéTODO PARA LIGAR CONTAMINANTES EM áGUA Descreve-se aqui composições e métodos úteis para a purificação de água usando-se macromoléculas dendríticas. O processo envolve o uso de macromoléculas dendríticas (dendrímeros) para ligarem-se a contaminantes, e uma etapa de filtração para produzir água da qual contaminantes foram removidos ou modificados. Exemplos de dendrímeros que poderiam ser usados no processo incluem dendrímeros de ligação de cátions, dendrímeros de ligação de ânions, dendrímeros de ligação de compostos orgânicos, dendrímeros com atividade redox, dendrímeros de ligação de composto biológico, dendrímeros catalíticos, dendrímeros biocidas, dendrímeros de ligação viral, dendrímeros multifuncionais, e combinações dos mesmos. O processo é facilmente ampliável em escala e proporciona muitas opções para personalização.
