The Study of Chemistry Precipitation Method Extraction Magnetic Ferric Oxide from Chromium Dregs
In view of chromium dregs is deleteriousness, harms humanity's health, this article uses chemistry precipitation method to carry on the disintoxicating for it, and prepares the magnetic Ferro ferric oxide. The feeling coupling plasma atomic emission spectrum method to analysis purity and yield of magnetite Ferro ferric oxide, and then discussed the concentration, temperature and concentration of precipitation agent yield and purity.
