Kanemite, NaHSi2O5·3H2O, has been found to extract the metal complex cation, hexamminecobalt(m){[Co(NH3)6]3±} directly from aqueous solution at ambient temperature. The enhancement of the extraction by the quaternary ammonium salt, hexadecyltrimethylammonium chloride, is related to the ability of the quaternary ammonium salt to decrease the effective interlayer charge at the layer edges, thus permitting greater diffusion of the complex cation. The extraction is reversible since the cobalt… CONTINUE READING
