Abstract

Se usa un medio para quitar especies de soluciones acuosas, particularmente en el tratamiento de agua para permitirle ser adecuada para beber. El medioincluye un material seleccionado del grupo que consiste en hidroxido de circonio, hidroxido de tita nio, hidroxido de hafnio y combinaciones de ellos. Una formapreferida del medioes una capa que tiene una relacion de aspecto de por lo menos 1:1, más preferiblemente , por lomenos alrededor de 10:1. Los quitado del aguason especies selecionadas del g rupo que consiste en arsenato, selenato, cromato, borato, perclorato, fluoruro y combinaciones de ellos. En particular especiesque contienen arsenito (As13), también son quitadas del agua. El arsenito puede ser quitado del agua hasta niveles no mayor es que 10 partes por billon con unasola exposicion al medio. El medio es selectivo para ciertas especies sobre otras. EL componente de arsenio es quitado a pesar de la presencia de por o menosuna especie competente seleccionada del grupo que consiste en sulfato, fosfato, nitrato, bicarbonato, hierro, carbonato, nitrito, silicato, sulfito, cloruro,bromuro y yoduro. El medio preferiblemente est{a en forma de polvo mientras se usa para tratar agua. El medio puede ser empleado en una variedad dedisp ositivos incluyendo filtros de agua de tipo cartucho y una prensa de filtro.
