摘  要：
建立气相色谱法同时分析白酒中三丁基锡(TBT)和三苯基锡(TPhT)。样品经正己烷萃取,四乙基硼酸钠衍生化,气相色谱-火焰光度法(GC-FPD)进行检测,并对影响测定的各种因素进行探讨。在0.1～10.0mg/L质量浓度范围内,TBT、TPhT的吸收峰面积与质量浓度线性关系良好,线性相关系数分别为0.9990、0.9995,检测限分别为0.0375、0.0489mg/L。在0.5、5.0、10.0mg/L三个添加水平下,TBT、TPhT的平均回收率为89.8%～100.9%,相对标准偏差为4.15%～9.04%。该方法用于白酒中有机锡化合物的分析,结果良好。

摘  要：
A method was developed for simultaneous determination of tributyltin (TBT) and triphenyltin(TPhT) in white spirit by using gas chromatography-flame photometry detection (GC-FPD). The sample was extracted by hexane, and derivatived by NaBEt4. The various factors influencing analysis results were investigated. The results present the good linearities between analytical signal and analyte concentration in the range of 0.1-10.0 mg/L with the correlation coefficients of 0.9990, 0.9995. For TBT and TPhT, limits of detection are 0.0375, 0.0489 mg/L, respectively. The average recoveries of TBT and TPhT at the spike levels of 0.5, 5.0 mg/L and 10.0 mg/L are in the range of 89.8%-100.9%, with the relative standard derivation of 4.15%-9.04%. A satisfactory result was obtained in the determination of organotin compounds in white spirit.
