| Abstract: | At present,the number of the waste printed circuit boards（WPCB） is increasing gradually.The technology of extraction and recovery of metal has been used widely,while the technology of extraction and recovery of a great deal of nonmetallic material is not viable.This paper briefly introduces the damage of WPCB and the recovery method of epoxy resin.The solvent method is adopted for the recovery of WPCB.The optimal conditions are defined as follows.The reaction temperature is 80℃,the reaction time 3 h,the concentration of nitrate acid 8mol/L,and the amount of nitrate acid 50mL when the amount of WPCB is 10 g. |
