Abstract

La presente invencion proporciona un material superabsorbente que comprende una combinacion de (1) un superabsorbente anionico, en el cual de 20% a 100% de los grupos funcionales están en forma de ácido libre, y (2) un intercambiador anionico, en el cual de 20 a 100% de los grupos funcionales están en forma básica. La combinacion es particularmente efectiva como un superabsorbente, en el caso de soluciones que contienen electrolitos, tal como menstruacion y orina.
