Abstract:

Chelating reagents supported (or banded) on silica gel for preconcentration and separation of trace amount of metal ions has been reported recent years. These methods improve analytical sensitivity and selectively greatly,and make it possible for many trace elements to be determineted in the Environmental fieled.
