Using high-quality wood, wood chips and coconut shell as raw materials, activated by steam method, be refined by advanced production process. With the advantages of large surface area, adsorption capacity, high mechanical strength, surface oxygen gene,  positive and so on, it is applied to the purification treatment of electroplating solution in electroplating industry,  to reduce impurities and improve the purity of electroplating solution, so that it can repeat the effective use and reduce production costs.
