摘　　要：废弃发泡聚苯乙烯塑料中含六溴环十二烷阻燃剂等有毒物质会严重影响其再生回收和利用。以十氢萘为溶剂、正丙醇为反溶剂,通过发泡聚苯乙烯的溶解与沉淀过程进行了六溴环十二烷的分离研究。结果表明:在温度为50℃,反溶剂用量体积与发泡聚苯乙烯溶液体积比为1:1,搅拌速度不低于2000rpm时,六溴环十二烷的分离率可达80%以上。The flame retardant like hexabromocyclododecane in waste expanded polystyrene is harmful for regeneration, recycling and utilization of polystyrene. Separation of hexabromocyclododecane is studied in the dissolution and precipitation process of expanded polystyrene, by using naphthalene as solvent and propanol as anti solvent. The results show that the separation rate could be up to 80%or more at the temperature of 50℃, the volume ratio of 1 with anti solvent and expanded polystyrene solution and the stirring rate of 2000 rpm or more.
