Sodium alginate industrial grade

Sodium alginate is widely used in many industries. It is a common additive in textile printing and dyeing, and it is also commonly used to remove mites from tea trees. In fact, sodium alginate is also very common in paper production and wastewater treatment.

Wastewater treatment:

The macromolecular structure of alginic acid contains a large amount of -COOH and -OH, and is a polyanionic compound that can complex well with metal ions. Some scholars explored the adsorption process of sodium alginate on Pb2+ and Cu2+, and found that carboxyl oxygen (-COO) and hydroxyl oxygen (-OH), ether bond oxygen (C The coordination between -0-R) and metal ions is the main way for sodium alginate to combine with heavy metal ions, and the adsorption of Pb+ by sodium alginate is an ion exchange process, but the adsorption of Cu2+ includes not only ion exchange, but also the coordination and chelation adsorption of other functional groups of sodium alginate, and the binding order of sodium alginate to three divalent ions are given: Pb2+>Cu2+>Ca2+. Li Guoqing used sodium alginate and sodium humate in combination to treat heavy metal wastewater containing Cu2+ and Cd2+, and found that the removal rate of the two ions by this treatment agent reached more than 95%. Jodra determined the order of the adsorption selectivity of sodium alginate to metal ions by calculating the equilibrium constant: Pb2+>Cu2+>Cd2+>Ni+>Zn+>Co2+.

Papermaking industry:

Water-soluble sodium alginate for desizing in the paper industry replaces part of the turpentine pulp or desizing the surface of the printing paper, which can improve the surface gloss of the printing paper, adjust the digestion and absorption of ink printing, wax, and oil, and improve the rubbing resistance of the printing paper.

Sodium alginate has good water-solubility and gel-forming properties. Using sodium alginate to carry out surface glue adjustment can form a continuous, permanent and flexible plastic film on the surface of the paper, which not only improves the calendering resistance of the surface of the printing paper. The compressive strength is improved, and the surface of the printing paper can be effectively printed with ink quickly, and the printed image is also more glossy and bright. It can also eliminate the internal strain of the printing paper caused by drying, prevent the expansion and shrinkage of paper or cardboard and eliminate the size deviation during printing. As a natural polymer, sodium alginate can adjust the surface of paper to reduce papermaking. COD load in the plant. Because of its good solubility, it is beneficial to the protection of the ecological environment.
