Abstract
Adsorption of the non-interacting amines, 2, 6-dimethylpyridine, 2, 6- dimethylpiperidine and 2, 6-dimethylmorpholine, in cyclohexane on some Indian Ocean manganese nodules has been studied. A linear relationshi p between the acidities and the surface OH concentrations of the sampl es suggests that the adsorption sites may be strong acid sites (Bronst ed sites). N-2 adsorption at 77 degrees K shows that these materials a re mesoporous with surface area values in the range 97-130 m(2)/g.
