| 摘 要： | 经典的重铬酸钾法(SnCl2—HgCl2法)测定铁矿石中铁的含量1],方法准确、简便,但所用氯化汞是剧毒物质,会严重污染环境,从而对(SnCl2—HgCl2)测铁法进行了一定的改进,将该实验中采用的还原剂SnCl2换成了廉价、易操作、易处理、无污染的锌片或锌粉。

| Abstract: | Determination of iron in ironstone by potassium dichromate method has been improved in our laboratory as a cheaper,operation and treatment more simple,without pollution method.Unlike classical potassium dichromate method polluted environment by noxious hydrargyrum chloride,improved method uses the sheet zinc or zinc powder instead of stannum chloride. |
