摘要
利用自制的活性炭纤维结合固相微萃取-气质联用技术(ACF-SPME/GC-MS)分析了水相中的一丁基三氯锡(MBT,monobutyltin trichloride)。对实验影响因素如萃取温度、离子强度、萃取时间进行了研究。结果表明,该方法的线性范围为0.1～100μg/L,检出限为4.5 ng/L,相对标准偏差为8.6%。将ACF-SPME/GC-MS技术用于实际海水样品的分析,取得了理想的效果。
The performance of activated carbon fiber（ACF） used as extraction fiber for solid phase microextraction （ SPME ） and its application for the determination of monobutyltin trichloride （MBT） in seawater were investigated by GC - MS. The influences of experimental factors, such as extraction temperature, ion strength and extraction time, on the SPME extraction efficiency were optimized. Under the optimal conditions, a good linear relationship was observed for MBT in the range of 0. 1 - 100 μg/L with the limit of detection of 4.5 ng/L . The RSD for the determination of 100 μg/L of MBT was 8.6% （ n = 6）. The method was applied in the determination of MBT in the seawater with satisfactory result.
