| 摘 要： | 过氧化苯甲酰具有强氧化性,与碘化钾反应生成苯甲酸和碘,根据碘与淀粉反应呈蓝色的原理研究制作快速检测试纸.将醋酸纤维素膜作为显色层,浸入由0.4％的糊化淀粉溶液、10％KI和4％的Na2CO3组成的混合显色剂,浸泡5 min后,真空干燥制备出检测试纸；标准比色卡由10个色块组成,过氧化苯甲酰质量浓度在0～228 mg/L范围内色阶明显,对面粉中过氧化苯甲酰最低检出限为36 mg/kg,相对误差范围为11.76％～16.89％.

| Abstract: | Benzoyl peroxide has strong oxidation ability,and can react with potassium iodide to generate benzoic acid and iodine.Therefore,the rapid test strip can be prepared according to the principle of the color reaction of starch and iodide.A cellulose acetate membrane was used as the color layer,then was soaked in a color reagent mixture solution containing 0.4% gelatinized starch solution,10% KI and 4% Na 2 CO 3 for 5 minutes,and was dried under vacuum to obtain the test strip.A standard colourimetric card cons... |
