“…For calculating AH°and A5°the following rela-tionships21 were used AF°= AH0 -ACPT In T + IT (7) and aH°= AHq°+ ACPT (8) where AH0, A Cp and I are constants which may be evaluated by solving equations using the values of AF°calculated by 6.…”

“…The order of elution of the rare earth metal ions with a citrate buffer of pH 3.28 is Lu3+ to Sm3+ in the inverse order of atomic numbers (273). a-Hydroxyisobutyric (87,351,512), glycolic (547), and lactic (157,626) acids have also been investigated. The separation factors for -hydroxyisobutyric acid are comparable to those of ethylenediamine-, , ', 'tetraacetate, and this eluting agent may be superior to the latter as a consequence of better flow rates and solubility characteristics (87).…”
