Cationized lignocellulosic materials (cotton fibers; wood sawdust; and maize-cob flour) are prepared by grafting quaternary ammonium groups for use as scavengers for anionic surfactants. Generally; rapid adsorption occurs and at saturation leads to a stoichiometric ratio of cationic sites and anionic surfactants such as sodium dodecyl sulfate; sodium dodecyl benzene sulfonate; and sodium oleate. Modeling of these adsorptions is tested using Lang muir; Freundlich; or Jossens equations; the latter giving the best fit with experimental data. The results are compared with the adsorption of chromate and dichromate anions on the same sorbents. © 2005 Wiley Periodicals; Inc;
