一、实验目的 了解和掌握荧光分光光度计的使用方法 二、实验原理 测Vc 的实验原理:抗坏血酸在氧化剂存在下,被氧化成脱氢抗坏血酸,氧化型的抗坏血酸与邻苯二胺作用生成荧光化合物(脱氢抗坏血酸对-氮杂萘),此荧光化合物的激发波长是350nm,荧光波长在430nm,其荧光强度与抗坏血酸含量成正比,样品的荧光强度与抗坏血酸标准样品荧光强度相比较,即可计算出样品中抗坏血酸的含量。 测VB2的实验原理 :维生素B 2 (核黄素)在468nm紫外光激发下产生
),将维生素B2还原为无荧光的物质,再测定试液中残余荧光杂质的荧光强度,两者之差即为食品中维生素B2所产生的荧光强度。 试剂 和器材 一、 试剂 0.1 mol/L盐酸; 1 mol/L氢氧化钠; 0.1 mol/L氢氧化钠; 20%(w/v)连二亚硫酸钠溶液; 洗脱液:丙酮+冰醋酸+水(5+2+9); 0.04%溴甲酚绿指示剂; 3%(v/v)高锰酸钾溶液
相关专题 维生素B12在一定波长的光照射下,会发出绿色荧光,制作多维葡萄糖粉试样的标准曲线,根据荧光强度可以计算多维葡萄糖粉中维生素B12的含量。 实验目的 Ø学习荧光分光光度法测定多维葡萄糖粉中维生素B2的分析原理。 Ø掌握荧光分光光度计 的操作技术和测定多维葡萄糖粉中维生素B2 的方法。 荧光分析法实验原理 常温下,处于基态的分子 吸收一定的紫外可见光的辐射
