Abstract

A rapid method for successive determination of Fe, Mn, Zn, Cr, Cu, Ni, Co, Pb and Cd using the common flame atomic absorption spectrophotometer on weight,d and once digested samples of marine sediments is described. After comparison we chose the HF-HClO₄一HNO₃ decomposition or the HNO₃-H₂O₂ digestion and studied certain interfering issues: deducting background absorptions in determining Co and Ni we measured nonabsorbable lines, using K₂S₂O₇, or sodium sulfate-sodium citrate solution to inhibit several elements interfering with the determination of Cr.
