POLYTE - Heavy Metal Chelating Agent Brochure

The POLYTE Cleanseries heavy metal chelating agentform a planar tetragonal structure with metal ionsof thedsp2valence bond orbital, andform a tetrahedral structure with a metal ionof thesp3valence bond orbital, and metal ions of d2sp3 valence bond orbital. Because the chelating agent forms a less spatial configuration with the metal ions of different valence bond orbital, the chelate formed by the reaction of the chelating agent with the heavy metal ions has higher stability. This kind of chelate has stable chemicalproperty, difficult to dissolve in water, low dissolution rate, and low risk forsecondary pollution. It is widely used in the removal of heavy metals such as zinc, lead, cadmium, arsenic, nickel, copper and chromium in wastewater and solid waste.
