ZG FS 821 resin for removing arsenic and fluorine

Description

ZG FS 821 is a specialized resin with a gel structure. It is a macromolecular copolymer with activated rare earth elements based on a styrene-DVB matrix. This chemical structure allows fluorine and arsenic in water to form stable complex compounds, reducing fluorine and arsenic concentrations in water, achieving the National Drinking Water Standard: arsenic less than 10 μg/L and fluorine less than 1 mg/L. The resin can also be used to recover arsenic and fluorine from wastewater.ZG FS 821 has a comparatively higher adsorption capacity and adsorption rate for fluorine and arsenic. It effectively reduces arsenic and fluorine levels in solution and meets safety requirements. Furthermore, the resin can be rinsed with a NaOH solution and then reused for element adsorption after regeneration with 5-10% sulfate acid to adjust the pH to 4-6.
