Yuhui A-SQ-H is a premium grade gel-type strong base anion (SBA) exchange resin based on styrene-divinylbenzene (DVB) copolymers with quaternary amine (Trimethylamine) function group and standard Gaussian particle size distribution. Due to its high exchange capacity, A-SQ-H can keep working to capture anionic contaminants for long term without regeneration, especially for chromium and uranium. A-SQ-H is developed to be used for hexavalent chromium, uranium removal from ground water or wastewater. Regeneration of A-SQ-H is not recommended because the eluted contaminants of chromium and uranium would cause environmental problem. A-SQ-H could be incinerated after being exhausted.
