The formation constants for the 8-quinolinol-5sulfonic acid chelates of lanthanum, cerium(III), praseodymium, neodymium, samarium, gadolinium, and erbium were determined at three different ionic strengths and at three different temperatures. The three thermodynamic functions, DELTA F/sup 0/, DELTA H/sup 0/ , and DELTA S/sup 0/, were calculated for the metal chelates at 25 deg and mu = 0. The bonding in the complexes was shown to be ionic in nature. (auth)
