Mercury Removal Agent
General Product Category: Auxiliaries / Industrial Water Treatment Chemicals
High Affinity for Mercury: Mercury removal agents feature extremely high affinity for mercury ions (Hg²⁺) and elemental mercury (Hg⁰), forming stable, insoluble mercury complexes or precipitates rapidly, achieving efficient mercury removal in both aqueous and gaseous media.
Stable & Wide Applicability: Most formulations remain stable across a broad pH range (typically 2–12) and maintain performance even in complex industrial environments with high salinity, heavy metals, and organic contaminants.
Versatile Industrial Uses: Widely applied in wastewater treatment, flue gas purification, natural gas processing, petrochemical refining, and mining industries to meet regulatory mercury discharge standards.
Form & Handling Convenience: Available in liquid, powder, or granular forms, with options for easy dosing and integration into existing industrial processes, suitable for continuous and batch treatment systems.
Mercury removal agents are specialized functional chemicals designed to capture and remove mercury from various industrial streams. Based on chemical composition, common types include sulfur-based precipitants, thiol-functional chelating resins, modified activated carbon adsorbents, and halogenated oxidizing agents. These products exhibit high selectivity for mercury, minimal interference from other pollutants, and low residual toxicity, making them essential for environmental compliance and industrial safety.
