Abstract

Patente de Invenção: <B>"MéTODO DE REMOçãO DE ìONS PREJUDICIAIS E AGENTE DE REMOçãO USADO PARA TAL"<D>. São descritos um método de remoção de íons prejudiciais tais como cobre, zinco, cádmio, cromo ou chumbo contidos na água de modo eficiente e com uma quantidade reduzida de formação de sedimentos e um agente de remoção usado para isso. O método de remoção é tal que uma substância polimérica hidrofílica contendo um grupo aniónico é dispersa na água em um estado não-dissolvido e os íons prejudiciais são insolubilizados ao mesmo tempo em que se mantém a substância polimérica hidrofílica no estado não-dissolvido. O agente de remoção de íons prejudiciais é caracterizado pelo fato de o agente ser um pó ou líquido contendo uma substância polimérica hidrofílica contendo um grupo aniónico.
