Rhenium (O-20 fig) may be determined as perrhenate spectrophotometrically at 362 nm after its extraction at pH 4 with amiloride hydrochloride into 4-methyl-2-pentanone. The relative standard deviation for 7 determinations of 10 pg of perrhenate is 1.5%. The effects of pH and diverse ions are reporte
