Rhodium, a member of the platinum group, is a silver-white, hard metal with high reflectivity, softness, good ductility and plasticity, and can be used as a bright and hard coating for other metals. It is an indispensable key material in high -tech fields such as automobile manufacturing. The resin method is to use ion exchange resin to recover rhodium from waste catalysts, waste electrical components, broken vessels containing rhodium, and waste electroplating solutions. It has the advantages of high separation efficiency, simple operation and recyclable resin. Rhodium adsorption resin produced by Bestion brand has high selective affinity and adsorption rate, and simple regeneration and high regeneration rate, and is widely used in industrial palladium metal recycling.
