Sushil Kumar Mukherjee
Sushil Kumar Mukherjee, Indian agricultural chemist (Barisal, Bengal 13 October 1914 – Kolkata 18 November 2006) Authored over 200 research papers Suggested potentiometric titration of clays with tetramethylammonium hydroxide in the presence of its salts Proposed non-equivalence of binding sites Applied the concept of Donnan equilibrium for the determination of ion activity in colloidal clays Reported that metal ions exchanged followed the order Cu 2+> Mn 2+> Zn 2+ Showed that non-ionic organic molecules of polar character could be absorbed on its basal plane surfaces Demonstrated the usefulness of viscosity measurements in estimation of the predominant clay mineral in artificial mixtures or soils Established that all humic fractions exhibited a peak at 465 nm using fluorescence excitation spectroscopy Demonstrated that clay bound with humus is much more resistant to microbial attack than humus alone Laid the foundation for the development of macromolecular structures of humic substances DEVELOPED A membrane with semiconducting properties under C.E.
