抄録

Nickel(II) hexacyanoferrate(II) has been found to be an effective adsorbent for number of biomonomers such as adenine, adenosine, 5′-AMP, 5′-ADP, and 5′-ATP. The adsorption is maximum at a pKa value specific to each biomonomer. The specific binding ability of adsorbate is related to the number of phosphate groups attached to an adenosine moiety. The overall adsorption trend is found to be in the order of 5′-ATP > 5′-ADP > adenine > 5′-AMP > adenosine. The infrared spectral studies of adsorption adducts suggested that adsorption takes place due to the complex formation between adsorbate molecule and outer divalent metal ion of nickel(II) hexacyanoferrate(II). Such adsorption processes could have helped in the protection of biomolecules from degradation on the primitive earth.
