CH520 features a macroporous styrene structure with specific chelating functional groups that offer much higher selectivity for target heavy metals (like Cu, Ni, Co) compared to standard resins, reducing contamination and increasing recovery purity.
Resin should be kept in a wet state at temperatures above 0℃. For long-term storage, it should be placed in a closed space or preserved in a salt solution of 5% or higher to prevent dehydration and degradation.
Yes, CH520 is manufactured to meet FDA standards for food-grade use, along with ISO9001, SGS, and WQA certifications, ensuring safety for sensitive purification processes.
To prevent the resin pores from becoming jammed with suspended solids, it is highly recommended to implement pre-treatment steps such as flocculation, filtration, or sand-filtration.
CH520 is designed to complement or serve as a high-performance alternative in similar workflows. It can be used in conjunction with Amberlite products to enhance multi-stage separation efficiency and improve ion selectivity.
Generally, the resin requires an alkali-water-acid-water flow path. For strict purification requirements, three full circulation cycles are recommended before the final ion kernel stage.
