Abstract
Bi and Fe were simultaneously detd. spectrophotometrically in Pb samples at 270 and 247 nm for 0.75-30 mg Bi/L and 0.5-25 mg Fe/L, resp. in the presence of DTPA (8 ´ 10-4 mol/L) and HClO4 (2.34 mol/L) in 1 cm quartz cells. Under these conditions Bi is complexed by DTPA but Fe is not. Potential interferences were studied.File allegati a questo prodotto
