Abstract
Adsorption of aqueous selenite (SeO32-) on Indian Ocean manganese nodu les was studied as a function of time, temperature, pH, and concentrat ions of adsorbate and adsorbent in acetic acid-sodium acetate buffer m edium. Analysis of adsorption data supports a heterogeneous nature for the surface of manganese nodules. The adsorption capacity of various manganese nodules for selenite was correlated with their chemical comp osition and surface properties. (C) 1997 Academic Press.
