Bio Bacteria for Heavy Metal Chelating

Product Introduction:

Heavy metal chelating agent can capture cations and tend to form bonds to generate insoluble phosphate polymerizers. Some of the phosphate polymerizing agents are ionic bonds or strong polar bonds. The coordinating bases chelated by the same metal ion may come from different phosphate molecules, so the resulting fractions will be highly cross-linked and three-dimensional, and the resulting insoluble chelating salts can reach millions or even more. Therefore, once this metal salt is formed in the fly ash, it has a good flocculation and precipitation effect.

The chelating precipitation method takes advantage of the rapid reaction of chelating agents with various heavy metals such as Hg2+, Cd2\ Cu2+, Pb2+, blood 2+, Ni2+, Zn2\ Cr3+ in fly ash at room temperature. It is a very stable compound with low solubility, and will not affect the stability of the combination with heavy metals when encountering external conditions such as acid and alkali. Strong reactivity to heavy metal ions. The solid reactant can be generated instantaneously, and the residual metal ion concentration is low after the reaction.

Mechanism of Action:

The product chelates heavy metal ions through a variety of chelating groups to produce a hydrophobic structure and precipitate; Thus getting rid of the disadvantages of linear chelation precipitation. The increase delays the hydration reaction of calcium silicate in the cement at an early stage, reducing the amount of cement input and providing fly ash handling capacity. Enhances cured product hardness and soaking resistance.
