摘　　要：碱性介质中双酚A对鲁米诺-高锰酸钾化学发光体系有很强的抑制作用．结合静态注射技术，建立了静态注射化学发光分析法测定食品包装材料中双酚A的方法．该方法测定双酚A的线性范围为1．0×10^-7～10×＾－３mol·L＾－１（r=0．993），检出限（3σ）为4．3×10＾－１tool·L＾－１，双酚A平行测定11次，其相对标准偏差为1．48％，回收率为76．35％～97．43％．The rapid and easy static injection chemiluminescence method was estabished to measure the content of Bisphenol A in food packaging materials. A mixture of luminal-potassium permanganate in the alkaline solution can create a stable chemiluminescence（CL） signal, and bisphenol A can in- hibit the CL signal when it is poured into the mixture. Under the optimized conditions, the linear range for the determination of bisphenol A was 1.0× 10^-7 to 1.0× 10^-3 mol· L^-1 （r =0. 993） with a detec- tion limit of 4.3× 10^ -3 mol· L-^1 The relative standard deviations for 11 repeated measurements was 1.48%. The method has been successfully applied to the determination of bisphenol A in food packa- ging materials with recovery rate ranging from 76.35% to 97.43%.
