  • A reversed phase high performance liquid chromatographic method was developed to determine dissolved acrylic acid in seawater. Using the Agilent SB-Aq-C18 column (100 mm×4.6 mm i.d., 5 μm) and 0.35% H3PO4-water (pH=2) as the mobile phase, the column eluate was monitored by ultraviolet detector. The wavelength of UV detector was 210 nm, and an external standard method was adopted. The detection limit of the method was 4 nmol/dm3(S/N=3). The peak area is linear with acrylic acid concentration in the range of 0.01~10 μmol/dm3, with a correlation coefficient of 0.999 6. The average recovery was 95.4%~98.1% and RSD was 1.3%~1.6%. Samples for acrylic acid could be stored in the dark at 4℃ after gravity filter through 0.2 μmWhatman membrane. The highly sensitive and accurate analytical method has been successfully applied to the determination of acrylic acid in natural seawater and algal culture.
