Constants of acid ionization and chelate formation of penicillamine and cysteine with gold (I) and other important metals at simulated biological conditions
… then used to determine metal complex formation constants of these ligands with the metals calcium(II), iron(III) and gold(I) by potentiometric titration using a standard glass and calomel reference electrode to determine hydrogen ion activity in solution. The results were treated with the …

Separation of alkali metal cations and alkaline earth cations using ionizable crown ethers
… and membrane transport processes, thermodynamic ionization constants, ^pKa, for twenty ionizable complexing agents were determined. Thirty functionalized polyether ligands were employed in the solvent extraction of group lA and 2A metal cations. For these highly lipophilic ionizable macrocyclic …
