Arsenic Removal Resin

Product Overview

Arsenic removal resins are available in metal-supported (Fe/Zr, compatible with As³⁺ / As⁵⁺ ) and strong-base anion exchange resins (As⁵⁺ only ) . They are primarily used for groundwater/drinking water, mine water, and industrial wastewater (photovoltaic/coal chemical), achieving effluent concentrations as low as 0.001 ppm. They exhibit high selectivity for heavy metals: the aminophosphonic acid groups have extremely strong affinity for **Fe³⁺ , Cu²⁺ , Zn²⁺ , Pb²⁺ , Sb³⁺ , and As³⁺ ** , far exceeding that for calcium, magnesium, and alkali metals, and remain stable even under high-salt conditions.

Product Information

For arsenic/antimony removal: they can directly adsorb As³⁺ and Sb³⁺ ( no pre-oxidation required), achieving effluent As ≤ 0.01 ppm and Sb ≤ 0.005 ppm, suitable for advanced treatment of groundwater/industrial wastewater.

High capacity + long lifespan: Heavy metal adsorption capacity up to 30–40 g/L; high mechanical strength, pollution resistant, lifespan 3–5 years, capacity recovery rate ≥95% after ≥30 regenerations.

Wide pH compatibility: Stable at pH 0–9, optimal in neutral/weakly acidic environments (pH 5–7), suitable for typical applications in complex industrial water quality: Groundwater/drinking water: Arsenic removal (As³⁺ / As⁵⁺ ) , antimony removal;Electroplating/metallurgical wastewater: Removal of Cu, Ni, Zn, Pb, Cd;Coal chemical/photovoltaic wastewater: Deep removal of Fe, Sb, As; Hydrometallurgy: Recovery of valuable metals (Cu, Zn, Co);Boiler feedwater/condensate: Deep removal of trace heavy metals.
