Abstract

MÉTODOS PARA REMOVER CONTAMINANTES A PARTIR DE SISTEMAS AQUOSOS. Métodos para remover um ou mais contaminantes a partir de uma corrente aquosa compreendendo: adicionar um polímero compreendendo unidades recorrentes de um ou mais monômeros de acrilamida e unidades recorrentes de um ou mais monômeros selecionados a partir de hidroxialquil metacrilatos e aliloxialquil diols para a corrente aquosa para formar contaminantes solidificados; e separar os contaminantes solidificados a partir da corrente aquosa são providos. Os métodos podem ser usados para remover contaminantes incluindo contaminantes com base em zinco, cobre, bário, alumínio, manganês, cobalto e ferro.
