Abstract

PROCEDIMIENTO DE PREPARACION DE UN ABSORBENTE CATIONICO PARA ELIMINAR MATERIAS ANIONICAS DE LAS SOLUCIONES ACUOSAS. CONSISTE EN HACER REACCIONAR UN COMPUESTO AMINICO, PORTADOR DE UN GRUPO AMINICO Y UN GRUPO CARBONAMIDICO EVENTUALMENTE METILONADO, CON UN PRECONDENSADO AMINOPLASTICO EXENTO DE GRUPOS AMINICOS. LA REACCION TIENE LUGAR EN MEDIO NEUTRO O ACIDO A UNA TEMPERATURA ENTRE 60 Y 120GC Y UTILIZANDO CATALIZADORES COMO PEROXIDO ORGANICOS E INORGANICOS. PUEDE UTILIZARSE PARA TRATAMIENTO DE AGUAS RESIDUALES, BAÑOS RESIDUALES DE OPERACIONES DE BLANQUEO O TINCION, AGUAS DE ENJUAGUE Y LAVAZAS.
