Abstract

Procedimiento para excluir de las soluciones acuosas los iones de metales pesados, caracterizado por tratarse las agua residuales con un adsorbente insoluble en agua que está constituido por el producto de reacción entre: 1) un compuesto polinitrigenado básico, acilable,. 2) un ácido carboxílico alifático o aralifático que contiene substituyentes móviles o un enlace múltiple adicionable y 3) un compuesto reticulante, distinto del componente 2), que presenta a lo menos dos substituyentes reactivos, conduciéndose el tratamiento, a una temperatura entre 10º y 100º c, de preferencia entre 20 y 70 ºC, y a un ph entre 2, y 12, preferentemente entre 2 y 9 y especialmente de 3 a 7, por agitación de las aguas con el adsorbente, o bien mantenido las aguas en corriente con el adsorbente en suspensión o bien pasándolas a través del adsorbente a modo de lecho filtrante.
