K. Grudpan et al., SPECTROPHOTOMETRIC DETERMINATION OF URANIUM BY FLOW-INJECTION ANALYSIS USING U TEVA.SPEC(TM) CHROMATOGRAPHIC RESIN/, Journal of radioanalytical and nuclear chemistry, 229(1-2), 1998, pp. 179-181
A flow injection analysis (FIA) system is described for the determinat
ion of uranium. The system consists of a microcolumn packed with, U/TE
VA.Spec (TM), chromatographic resin for on-line sample separation. The
eluate is mixed with 4-(2-pyridylazo) resorcinol (PAR). The colored p
roduct is continuously monitored spectrophotometrically.
