摘要
采用固相微萃取-毛细管柱电子捕获气相色谱法测定水源地水中18种半挥发性有机物,优化了萃取纤维、时间、温度、pH值、转子转速、离子强度等萃取条件。方法线性良好,18种化合物的检出限为0.000 2μg/L^0.1μg/L,实际水样加标回收率为84.3%~109%。
18 semi-volatile organic compounds in source water were determined by GC/ECD with solid- phase micro-extraction technology. By optimizing extraction condition of fibers, time, temperature, ph value, ro- tor speed and ion intensity, the results showed good linearity; detection limits of 18 compounds between 0. 000 2 μg/L and 0.1μg/L; and spiked recoveries of samples between 84.3% and 109%.
