中文摘要：

建立了顶空固相微萃取（HS-SPME）-气相色谱法测定人工湿地废水中烷基硫醇化合物的分析方法。详细研究了萃取参数如萃取涂层、萃取时间、萃取温度、样品体积、盐效应及样品pH值等对HS-SPME萃取乙硫醇（EtSH）、2-甲基-2-丙硫醇（Me-PrSH）、1-丙硫醇（1-PrSH）、2-丙硫醇（2-PrSH）、1-丁硫醇（1-BuSH）及环戊硫醇（CycloPeSH）（内标）的影响。富集的硫醇化合物经DB—VRX毛细管色谱柱分离，FPD检测。在优化的实验条件下，测定乙硫醇、2-甲基-2-丙硫醇、1-丙硫醇、2-丙硫醇、1-丁硫醇的线性范围介于0．12～16．21μg／L之间；检出限（3σ）介于0．97～22．11ng／L之间。以环戊硫醇为内标物质，将本法用于废水中硫醇化合物的测定，获得满意结果。

英文摘要：

A headspace solid phase microextraction combined with gas chromatography/flame photometric detection（FPD） has been developed for the analysis of alkyhhiols in wastewater from constructed wetlands. The effect of various extraction parameters such as extraction coatings, extraction time, temperature, sample volume, salt effect, sample pH value on the extraction of alkyhhiols, namely, ethanethiol（EtSH） , 2-methyl- 2-propanethiol（ Me-PrSH ）, 1 -propanethiol （ 1 -PrSH ）, 2-propanethiol （ 2-PrSH ）, 1 -butanethiol （ 1 -BUSH ） and cyclopentanethiol（CycloPeSH） were investigated and optimized. The enriched alkylthiols were separated by DB-VRX capillary column and detected by FPD. Under the optimized conditions, the linear dynamic ranges for EtSH, Me-PrSH, 1-PrSH, 2-PrSH, 1-BUSH were in the range of 0.12 - 16.21 μg/L. The detection limit （3σ） for the studied five alkylthiols was 0.97 -22.11 ng/L. By using CycloPeSH as internal standard, the proposed method has been successfully applied to the analysis of alkylthiols in wastewater from constructed wetlands with satisfactory results.
