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.
