摘要
为研究吡啶类化合物添加剂抑制Co(Ⅱ)配合物氧化的能力,用光谱法研究了二环已基二硫代磷酸酯-吡啶类化合物萃取体系中Co(Ⅱ)配合物的氧化反应 吡啶类化合物添加剂能有效迟缓Co(Ⅱ)配合物的氧化,不同吡啶类化合物添加剂对Co(Ⅱ)配合物的氧化抑制能力不相同,其顺序为:4-甲基吡啶>吡啶>3,5-二甲基吡啶>2,4-二甲基吡啶>2,4,6-三甲基吡啶
The restraint ability of pyridine and its derivatives against the oxidation of cobalt(Ⅱ) complex is studied. The oxidizing process of cobalt(Ⅱ) complex is discussed in the bis-cyclohexyldithiophosphoric acid-pyridine solvent extraction system by using the method of spectrophotometry. The oxidizing process of cobalt(Ⅱ) complex can be restrained efficiently by pyridine and its derivatives. The process of restraint against the oxidation of cobalt(Ⅱ)complex is explained. The restraint ability of pyridine and its derivatives against the oxidation of cobalt(Ⅱ)complex are different; the order is established as:4-methylpyridine>pyridine>3,5-lutidine>2,4-lutidine>2,4,6-lutidine.
