use:

1. Used in organic catalysts, pyrotechnics and pigments. In agriculture, it acts as a preventive agent for plant smut, insecticide and antidote to phosphorus poison. It can be mixed with asphalt to prevent livestock and wild saplings; it is used as an additive for copper in feed, and it is used as a de-alkali agent in crude oil storage. And raw materials for the production of copper compounds. It can also be used for electroplating, antiseptic and analytical reagents.

2. As a feed additive, the absorption and utilization rate of copper carbonate by cattle and other ruminants is higher than that of other inorganic copper. However, due to its high cost, its application has been limited.

3. Used as an analytical reagent. Used in the preparation of copper salt preparations, paint pigments and pyrotechnic materials. Used as a phosphor activator, a seed bactericide.

4. Preparation of an oxidizing solution for pre-plating silver copper alloy, copper-plated tin alloy and steel.

Preparation:

1. Add the copper sulfate solution to a 50% aqueous solution of sodium bicarbonate with stirring:

The reaction temperature is 70-80 ° C, the addition rate of copper sulfate is not suitable for the foam generated by the generated CO 2 , and the reaction liquid is kept at ph=8. After the reaction is finished, the reaction liquid is boiled for 10 to 15 minutes, and the Basic Copper Carbonate is rapidly formed. Precipitate. After standing, the upper layer solution is clarified and separated, and the precipitate is washed with 70-80 ° C water or deionized water until it does not contain SO42- ions, and then separated by centrifugation, and dried at 80-100 ° C.

2. Copper nitrate method. Operation method: electrolytic copper reacts with concentrated nitric acid to form copper nitrate, and then reacts with a mixture of sodium carbonate and sodium hydrogencarbonate to form basic copper carbonate, and the precipitate is washed, separated and dehydrated, and dried to obtain a basic copper carbonate product.
