摘要: 海洋环境及沉积地球化学的调查研究,常需同时了解多种元素在海洋底质中的含量及其分布规律.对于某些非金属及半金属元素,我们曾研究过应用碱性有机染料的萃取-光度测定法[1-3].原子吸收分光光度法则可以快速、准确地测定海洋沉积物中的许多种金属的含量[4-6],一般不需要大量的预处理.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.
