Abstract:

建立了一种测定海水介质中丙烯酸的高效液相色谱法。采用耐纯水相和较低pH的AgilentSB-Aq-C18柱(100mm×4.6mmi.d.,5μm),0.35%磷酸溶液(pH=2)为流动相,使用紫外检测器,检测波长为210nm,外标法定量测定。丙烯酸的保留时间在14.2~14.9min,方法的检出限为4nmol/dm3(S/N=3),在0.01~10μmol/dm3的范围内均有良好的线性关系,相关系数可达0.9996,加标回收率为95.4%~98.1%,相对标准偏差为1.3%~1.6%(1.04~2.32μmol/dm3)。采用0.2μm滤膜重力过滤冷藏的办法来保存海水丙烯酸样品。检测出2011年5月份青岛近海海水中丙烯酸的平均浓度为(0.101±0.069)μmol/dm3;海洋微藻球形棕囊藻在整个生长周期内培养体系中丙烯酸的浓度为0.339~2.219μmol/dm3。
