Water Treatment Feed Grade Blue Crystal Copper Sulfate, Purity 96% CuSO4.5H20 Pentahydrate Copper Sulfate
1. Copper Sulfate Pentahydrate Introduction
Copper(II) sulphate, also known as copper sulfate, is the chemical compound with the chemical formula CuSO4. This salt exists as a series of compounds that differ in their degree of hydration. The anhydrous form is a pale green or gray-white powder, whereas the pentahydrate (CuSO4·5H2O), the most commonly encountered salt, is bright blue. Copper sulfate exothermically dissolves in water to give the aquo complex [Cu(H2O)6]2+, which has octahedral molecular geometry and is paramagnetic. Other names for copper(II) sulfate are "blue vitriol" and "bluestone". It is widely used in agricultural industry, electroplating industry, feed additive, etc.

3. Copper Sulfate Pentahydrate Application
3.1 Agriculture: Copper sulfate pentahydrate has a wide range of applications in the agricultural field. It can be used as an important trace element fertilizer to supplement copper in soil. Copper is one of the essential elements for plant growth and development, which can promote basic physiological processes such as photosynthesis, respiration, and nitrogen metabolism in plants. Therefore, moderate use of copper sulfate pentahydrate can increase crop yield and quality, prevent diseases caused by copper deficiency, such as copper deficiency syndrome.
3.2 Feed Additive: Copper sulfate pentahydrate also has important applications in animal husbandry. It can be used as a feed additive to supplement copper in animals. Copper is involved in the activation and catalysis of many enzymes in animals, and has important effects on the growth and development, immune function and reproduction of animals. Appropriate use of copper sulfate pentahydrate can prevent and treat copper deficiency in animals and improve the performance and health of animals.
3.3 Chemical industry: copper sulfate pentahydrate can be used as a catalyst, oxidant, reducing agent, etc. It is widely used in organic synthesis, electroplating, dye industry, and other fields. For example, copper sulfate is an important component in the preparation of inorganic pesticide Bordeaux mixture, which has bactericidal ability and can be used to control various crop diseases.
3.4 Water Treatment: Copper sulfate pentahydrate is also widely used in water treatment projects. Because of its strong sterilization ability, it can be used for the control of bacteria, algae and parasites in water bodies. Copper sulfate pentahydrate can effectively inhibit the growth of microorganisms in the water body, remove the muddy matter in the water body, and improve the sanitary index of water quality. Therefore, it is often used in the treatment of drinking water, swimming pool water and industrial circulating water.
4. The Role of Copper Sulfate in Aquaculture
4.1. For bactericidal purposes: Copper sulfate pentahydrate water soluble Cu2- ions are heavy metal ions that can inactivate proteins. Viruses are composed of proteins, so they can kill bacteria and viruses.
4.2. Algal killing effect: copper sulfate pentahydrate has a strong killing effect on algae and is often used in aquaculture to kill malignant algae such as blue-green algae. Please choose to do it on a sunny morning and take measures to increase oxygen levels. Generally, the algal killing concentration is 0.8ppm. Due to the large number of algae dying, it can cause oxygen deficiency in the pond. Therefore, some algae may produce toxic algal substances after death, so it is necessary to change the water or detoxify the water body appropriately.
4.3. Insecticidal effect: Copper ions can disrupt the activity of insect enzymes, thereby disrupting their material metabolism, and can poison various flagellates, ciliates, and some crustaceans. Generally used in combination with ferrous sulfate, a mixture is prepared in a 5:2 ratio, with 0.5ppm copper sulfate and 0.2ppm ferrous sulfate sprinkled throughout the tank.
