Copper (II) has been spectrophotometrically determined after extraction of its l-phenyl-4,4,6-trimethyl-lH,4H-pyrimidine-2-thiol complex into isobutyl methyl ketone (MIBK). Extraction is maximum (〜94%) in the presence of 0.2-0.5 M NaOH in aqueous phase. Optimum concentration range for determination at ^λmax 400 nm is 2.5-10.2 ppm. The molar absorptivity and Sandell's sensitivity are 7 × 10^3 1 mole^<-1> cm^<-1> and 0.009μg cm^<-2> respectively. Interference of cations and anions found commonly associated with copper has been studied. Copper contents in the samples of human hair, goat liver, blood sera and alloys have been estimated.
