Sorption of uranium by water hyacinth roots, calcium alginate in gel and dry forms, and immobilized water hyacinth roots by calcium alginate gel and dry forms were investigated. The sorption of uranium was examined as a function of pH, initial concentration, and weight of sorbents, solution volume, and temperature to study the effect of immobilization on the sorption. Kinetics and sorption isotherms were also discussed. When studying concentration, weight, and volume impact, calcium alginate in gel form showed the highest sorption percentage followed by immobilized water hyacinth roots in gel form. On the other hand, water hyacinth roots immobilized in calcium alginate in dry form showed higher sorption percentage than that of calcium alginate dry form when studying pH, concentration, and time effect.
