摘　　要：固相萃取（SPE）技术与气相色谱-质谱（GC-MS）、气相色谱-傅立叶红外光谱（GC-FTIR）技术结合，用于丁苯橡胶（SBR）生产过程中废水中的有机物的定性分析。每次使用0．18～0．15mm粒径的GDX-502吸附剂2g，1000mL废水，25mL二氯甲烷进行洗脱，洗脱液浓缩至1mL后用于GC-MS和GC-FTIR定性分析。分离在50m×0．20mmi．d．×0．5μm的HP-PONA柱上进行。从SBR废水中确定23种化合物，GC-MS与GC-FTIR联用，提高了定性的准确度。Solid-phase extraction （SPE） coupled with capillary gas chromatography （GC）-Fourier transform infrared（FTIR） and mass spectral （MS） detection was used for the analysis of the waste water from the production of styrene-butadiene rubber （SBR）. The solid-phase extraction procedure with 2 g pore size of 0.15 - 0.18 mm GDX-502 cartridges was used. 1000 mL water sample was passed through GDX-502 cartridges, and then 25 mL dichloromethane was used for desorption. The desorption liquid was condensed to 1 mL for identification by GC-MS and GC-FTIR. The separation was performed on a 50 m×0.20 mm i.d.×0.5 μm HP-PONA column. 23 compounds in extracts from SBR waste water were identified. The accuracy of identification was improved by using GC-MS and GC-FTIR at the same time.
