| titleOfInvention | A kind of production method of ultrapure ferric chloride |
| abstract | The invention discloses a method for producing ultrapure ferric chloride, which comprises adding iron-containing chloride into elemental iron for reaction, filtering to obtain ferrous chloride, and oxidizing the ferrous chloride into ferric chloride; Ferric chloride and elemental iron react, filter to obtain ultra-pure ferrous chloride solution, and obtain ultra-pure ferric trichloride through oxidation; if the obtained ultra-pure ferric trichloride cannot meet the requirements, the process of ferric chemical and oxidation can be repeated many times , so that the product meets specific requirements. The production material of the invention is economical and easy to obtain, the process is simple, the equipment investment is low, and the production safety is high. The ferric chloride produced by the process of the invention has the advantages of low acidity, low impurity, high content and the like at the same time, and the product can be applied to the fields of drinking water treatment, pharmaceutical intermediates, analysis and testing, precision etching and the like. |
