- 中文摘要: A new atomic absorption spectrophotometric procedure has been developed for the microdetermination of copper(II) as its oxinate by its adsorption on microcrystalline naphthalene and dissolution in 1N nitric acid. Copper(II) oxinate is quantitatively adsorbed in the pH range of 3.2-10.1 and trace amounts of copper time, digestion time, and diverse ions are studied. The proposed method has been applied to the determination of copper in standard reference material (zinc alloy), and metallic zinc and lead.
