. Many cryptands are commercially available under the tradename \\"Kryptofix\\" [4] . In this paper, we report the

results of thermodynamic study of complexation reactions between kryptofix 21 with Y3+ and Ce3+ cations in methanol-acetonitrile (Me...

, kryptofix -21,in pure acetonitrile , ethanol and also in acetonitrile- ethanol (AN-EtOH) binary mixtures have been studied at

different temperatures using conductometric method. the conductance data show that the stoichiometry of the complexes in most...
