1. A method of adsorbing chloride ions from an aqueous solution, comprising:
contacting a nanocomposite with the aqueous solution to form a mixture;
wherein the nanocomposite adsorbs at least a portion of the chloride ions in the aqueous solution;
wherein the nanocomposite comprises:
iron nanoparticles;
aluminum nanoparticles; and
guar gum;
wherein the nanocomposite is in the form of extruded cylindrical particles in which the iron nanoparticles and the aluminum nanoparticles are dispersed in a matrix of the guar gum; and
wherein the nanocomposite comprises:
15-25 wt. % iron nanoparticles;
15-25 wt. % aluminum nanoparticles; and
50-70 wt. % guar gum, based on a total weight of the iron nanoparticles, aluminum nanoparticles, and guar gum.
