Abstract
Conditions for the preconcentration of beryllium on a fibrous sorbent (poly acrylonitrile-carboxylated polyethylene-polyamine, PAN-carb-PEA) in the flo w-injection mode have been found. A procedure for the flow-injection photom etric determination of beryllium with Arsenazo I with sorption preconcentra tion has been developed. The detection limit of beryllium in natural waters is 0.1 mu g/L; the analysis time for a single sample is 9 min.
