Abstract
The sensitive separation of Be and other alkaline earth metals on a complexing sorbent with iminodiacetate (IDA) functional groups using indirect conductimetric detection is described. The selectivities of the separation of Be and other alkaline earth metals on IDA and surface-sulphonated sorbents were compared. The influence of the nature of the mobile phase complexing agent on the selectivity of the separation between Be and other alkaline earth metals was studied. An eluent containing dipicolinic acid and nitric acid proved to be optimum for the elimination of interferences from transition metals. The detection limit for Be was 10 μg/l. Preconcentration of Be on the complexing IDA sorbent increases the sensitivity of determination. This technique was successfully applied to the analysis of rock and natural water samples.
