J. Ryczkowski et D. Nazimek, QUALITATIVE ANALYSES OF IMINODIACETIC (IDA) AND NITRILOTRIACETIC (NTA) ACIDS ON ALUMINA BY FT-IR, Mikrochimica acta, 1997, pp. 227-228
Adsorption of IDA and NTA and their sodium salts on a gamma-alumina su
pport has been investigated by transmission FT-IR. The results obtaine
d imply, that the observed changes in the IR spectroscopic properties
of the adsorbed chelates are mainly due to interaction of the chelate
molecules with alumina hydroxyl groups.
