The present invention relates to a material for acquisition of liquids comprising individualized, crosslinked cellulosic fibers having an effective amount of a polymeric acid crosslinking agent (such as polyacrylic acid polymers) reacted with the fibers in intra-fiber crosslink ester bond form. The material further comprises at least one basic substance, selected from basic polymers (such as polyallylamine (PAAM) or crosslinked quaternary ammonium hydroxide divinylbenzene/styrene copolymer/Amberlyst A-26 OH). The invention also relates to disposable absorbent articles, such as diapers, containing this material. The material can be used in a method of reducing the electrolyte concentration of aqueous mediums containing electrolytes, such as urine.
