摘要：

本文报道南极海洋冷水环境中的低分子挥发性脂肪酸的一种测定方法 ,阐述高压液相色谱法对海洋环境中 C1- C5年低分子挥发性脂肪酸的含量测定具有较好的适用性 ,说明该方法具有正确、灵敏、操作简单、快速及需要样品量少等特点。本方法的最低检测限在 0 .1 μg/ml以下 ,个别酸如丙烯酸可达 0 .0 0 1μg/ml以下。南极戴维斯站附近沿海 ,1 989年 1月 3日 6 0 m水柱体样品测定结果丙烯酸为 0 .0 0 4 - 0 .0 4 2 μg/ml,其他酸是 0 .1 - 1 .0 μg/ml,说明了该方法完全可满足实际海水样品的分析。

Abstract:

A determinative method of low molecular volatioe fatty acids was been reported in this paper, It was shown that PHLC is applicable to measuring the concentrations of low molecular fatty scids in cold water environment in antarctica. This method has some specialitys such as accuracy; high sensitvity; easy and quicker with operation and a little samples are only required to used determination. The lowest limitation of determination for this method is 0.001μg/ml for acrylic acid and 0.1μg/ml for other volatile fatty acids. The results of determination shown that the concentration of acrylic acid is 0.004-0.042μg/ml through 60m depth in antarctic coast warter in 3 January 1989 and other volatile fatty acids are 0.1-1.0μg/ml.
