ABSTRACT
An improved spectrophotometric method of determination of U(VI) with 4-(2-pyridylazo) resorcinol (PAR) in a mixed micellar medium (mixed cationic and nonionic surfactants) in presence of EDTA/NaF as masking agent has been carried out in normal and derivative modes. The molar absorption coefficient (ε) and Sandell’s sensitivity (S) of U(VI)-PAR complex at 541.0 nm are 4.33 x 104 L.mol-1 cm-1 , 0.0055 μg.cm-2, respectively. The proposed method has been successfully applied to the determination of uranium in tap water, river water, seawater and synthetic sample.
