Abstract: Hyptis suaveolens seeds could serve as natural immobilized source of agriculturally based polysaccharide. Maximum adsorption capacity (6 gl⁻¹) of the seeds for arsenic adsorption has been found at pH 3.5 - 4.5. Among the tested interfering common metal ions, Ca⁺⁺, Mg⁺⁺ and Cl⁻ decreased adsorption rate about 48%, 54% and 30% respectively, whereas Zn⁺⁺ and Co⁺⁺ ions have no significant effect. Adsorption isotherm studies revealed a better correlation with Langmuir isotherm plot.
