Radium is a highly radioactive element, is the production of by-product of uranium. from genesis leaching of uranium in uranium ore with sulfuric acid, namely into sulfate radium exists in slag, and then transformed into chlorination radium, using barium salt as the carrier, with fractional crystallization, is pure radium salts.  
the present processing fields in all kinds of laser method are many, but from the point of economic investment and treatment effect, resin adsorption method advantage prominent, main show is low environmental requirements, simple operation, high processing precision, wide application market.
Jiangsu Bojie resin chemical co., LTD has its own brand Bestion.. Their professional PW981 except the radium resin has high selectivity, simple regeneration adsorption and elution, the advantages of the reusable, applies to every field of the adsorption process of radium.
