| 摘 要： | 研究了各类海藻中总硒的含量及硒的赋存形态的分布。采用连续浸提法研究各海藻中硒的赋存形态,经湿法消化后,采用氢化物-原子荧光分光光度法测定各组分中的含硒量。结果表明,12种海藻样品中,总硒含量范围为:0.0268～0.2234μg/g,海藻中硒的各赋存形态分布情况:碱溶态>残渣态>水溶态>盐溶态>乙醇态。

| Abstract: | The total selenium and the distribution of combined forms in marine algae were studied. The sequential chemical extractions had been developed for partitioning selenium in marine algae into five fractions:ethanol soluble,water soluble,salt soluble,NaOH solution soluble and residual. The selenium contents of all fractions were determined by hydride generation atomic fluorescence spectrometry (HG-AFS) after wet-digestion. The contents of total selenium of the 12 kinds of marine algae samples were in the range... |
