Heavy Metal Chelating Agent 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.
