RISComplexation ability of kryptofix 21 with Y3+ and Ce3+ cations in some pure and binary mixed non-aqueous solvents
. 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...
Study of complexation processes between kryptofix 222 with Cd 2+ and Y3+ metal cations in some pure and binary mixed non-aqueous solvents using conductometric method
are three dimensional analogues of crown ethers [4]. Most of them are
available as the commercial name ‘kryptofix’. In the present work, the complexation reactions between Cd2+ and Y3+metal cations with the macrocyclic
ligand, kryptofix222 (4...
