Interaction of D-glucose and b-glucuronic acid and of hydrolysed alumi
nium (III) has been studied in 0.6 M NaCl solution, Isolated solids we
re analysed and studied by means of IR and C-13 NMR spectroscopy. Solu
ble samples close to the precipitation boundary were examined with UV
spectroscopy. Glucuronic acid showed higher affinity toward binding to
the aluminium hydroxide matrix than glucose, It is concluded that glu
cose is bound via hydroxyl groups on C(4) and C(6) atoms in alpha- and
beta-pyranose forms. Glucuronic acid is bound in alpha- and beta-pyra
nose forms via the carboxyl group and the hydroxyl group on the C(4) a
tom.
