In this process, the amount of carbonated ammonia water is large, the price of carbonated ammonia water is cheap, and it has good selectivity for copper. Iron, aluminum, calcium, silicon, and other impurities can be removed and recycled. However, due to the strong smell of ammonia water. Therefore, the system must be recycled in a closed environment, with high requirements for equipment and large investment, which is not suitable for large-scale production.

Why use copper sulfate to make plant specimens?

The core of plant chlorophyll is a ring structure containing a magnesium ion. However, the chemical properties of magnesium ions are active and easy to present a free state. After the chemical reaction, the chlorophyll will be degraded, and the leaves will wither and yellow naturally. However, by contrast, copper ion is stable, once replaced by a magnesium ion, it will not easily occur chemical reaction. Chlorophyll containing copper ions will also show green. Therefore, copper sulfate is often used in the color protection of plant specimens. The green processing of plants is a green processing technology, in which free copper ions in industrial raw materials such as copper sulfate and copper chloride form chlorophyll metal complexes with chlorophyll.
