Description

An adsorptive stripping voltametric procedure for direct determination of trace quantities of uranium in sea water has been described. Optimal conditions include pH 6.7, 2 x 10-5M 8-hydroxy quinoline (oxine) and collection potential of -0.4V (Vs Ag/AgCl) at hanging mercury drop electrode. With controlled adsorptive accumulation for one minute a detection limit of 2.8 x 10 -10M uranium is obtained. The response is linear upto 7 x 10 -8M uranium and the relative standard deviation at 4 x 10-9M is 11.5%. The effect of possible interference from other metals has been investigated.
