Surface Interaction of Adenine on Montmorillonite Clay In Presence And Absence of Divalent Cations In Relevance To Chemical Evolution

[Full Text]

Key words: Adsorption, Biomonomers, Chemical evolution,Divalent Langmuir coefficients, Montmorillonite.,Oligomerisation



Abstract: Bernal suggested that clays might have played a significant role in primitive earth through the process of concentration and adsorption of the biologically formed biomonomers and thus protecting them against hydrolytic fission.Adsorption of adenine was studied in presence of montmorillonite clay with or without cations Ca2+,Cu2+,Mg2+.Studies carried out have shown that adsorption of adenine was dependent on pH and shows Langmuir adsorption isotherm. Percent binding and values of Langmuir adsorption isotherm on montmorillonite clay with or without divalent cations show that adsorption trend largely depend on the nature of adsorbate and the adsorbent.
