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。

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%.
