摘要 采用固相微萃取(SPME)法富集、气相色谱/质谱定量测定水体中的五种痕量异味有机物:2-异丙基-3-甲氧基吡嗪(IPMP)、2-异丁基-3-甲氧基吡嗪(IBMP)、2-甲基异冰片(2-MIB)、2,4,6-三氯苯甲醚(2,4,6-TCA)、土味素(Geosmin).对五种物质的检出限均在5.0ng/L以下,加标回收率为86.7%~96.2%,相对标准偏差为3.9%~7.1%. Solid phase microextraction (SPME) followed by gas chromatography/mass spectrometry (GC/MS) was used to detect the five odor forming organic compounds in water, which are 2-isopropyl-3-methoxypyrazine ( IPMP), 2-isobutyl-3-methoxypyrazine ( IBMP), 2omethylisoborneol ( 2-MIB ), 2,4,6-trichloroanisole (2,4,6-TCA), and trans-1, lO-dimethyl-trarts-9-decalol ( Geosmin ). The detection limits of the method for the detected compounds are all less than 5.0 ng/L, the standard addition recovery is in a rang of 86.7% -96.2%, and the relative standard deviations are in a range of 3.9% -7.1%.
