摘要
对 BCO光度法测定铁矿石中铜的分析方法进行改进 ,采用硝酸溶解处理铁矿石试样 ,Fe3+ 、Al3+ 采用 OH- 离子沉淀去除 ,用氨性缓冲溶液调节 p H值为 8.5～ 9.3,进行铜 ( )与 BCO显色反应 ,可以实现铁矿石中铜含量的快速测定。
The quick measurement of Cu in iron ore can be carried out by improving the method of measuring Cu with BCO lightness method,dissolving sample with nitric acid,removing Fe\+\{3+\},Al\+\{3+\} with OH\+- ion precipitating method,adjusting pH value being 8.5~9.3 with ammonia buffer solution and forming BCO colour reaction with Cu(Ⅱ).
