| titleOfInvention | A kind of preparation method of high-purity low chlorine oxide of high activity copper |
| abstract | The invention discloses the preparation method of a kind of high-purity low chlorine oxide of high activity copper, comprise the following steps: copper-containing raw material, chelating agent, auxiliary agent and deionized water are added mix homogeneously in reactor and obtains mixed liquor, it is slowly added to precipitant solution in described mixed liquor, filter after reacting 2 3h at 40 80 DEG C, wash with water to pH be 7.0～7.5, in 100～120 DEG C be dried 1～3 hour, then at 300～600 DEG C calcining 0.5～2 hour after obtain high-purity low chlorine oxide of high activity copper.Product quality and performance that the present invention produces are the most excellent, and product purity >=99.0%, the chloride ion content that prepare are less than 15 seconds less than 20ppm, dissolution time. |
