摘　　要：采用氧弹燃烧法对塑料样品进行燃烧,用碳酸钠作为吸收液进行吸收,建立了离子色谱法分离测定微量卤素离子的方法。离子色谱条件为:IonPacAS22离子交换柱,碳酸盐等度淋洗,抑制型电导检测。用该方法对塑料颗粒和塑料瓶盖中的氯离子进行测定,加标回收率分别为92.25%～95.68%、92.37%～95.52%。The determination method of trace halides in plastics by oxygen bomb combustion - ion chromatography with sodium carbonate aqueous solution as adsorption solution was established. The selected chromatographic conditions were as follows： IonPac AS22 anion - exchange column, isocratic elution with carbonate as eluent and suppressed conductivity detection. The proposed method was used to determine halides in plastics granul and palstics bottle cover, recoveries were 92.25% -95.68% ,92.37% -95.52% respectively.
