| 中文摘要: |
| 采用连续浸提分离技术,将苹果中的Se以水溶态、有机物结合态和残渣态3种形态选择性地提取,并用HG-AFS法检测了各形态的硒含量和总硒含量。结果表明:该方法硒的检出限为0.028 ng/mL,线性范围为0~10 ng/mL,精密度为2.8%,回收率为94.15%~108.95%;苹果中硒的3种形态含量不同,水溶态 > 有机结合态 > 残渣态,三者的加和略小于总硒含量,误差在2.6%以内。 |
| 英文摘要: |
| Selenium in apple was divided into three fractions: (1) water soluble, (2) organic compound, (3) residual by using sequential extraction separation technology, all the three forms of selenium and total selenium were determined with HG-AFS. The experimental results indicated that detection limit of selenium was 0.028 ng/mL, the linearity range was 0~10 ng/mL, the precision was 2.81%, and recovery percent was 94.15~108.95%. The content of three forms of selenium in apple were different, water soluble > organic compound > residual, and the sum of three was slightly smaller than total selenium, the error was less than 2.6%. |
