摘　　要：研究了顶空固相微萃取-气相色谱(HS-SPME-GC)法检测非木材植物纤维原料蒸煮黑液中的甲醇含量,优化了顶空固相微萃取的萃取条件及气相色谱的检测条件。结果表明:在气液平衡温度60℃,气液平衡时间30 min,萃取时间11 min,解吸温度280℃,解吸时间5 min的条件下检测结果最佳。A new method named ＂headspace solid-phase microextraction-gas chromatography＂（HS-SPME-GC） was developed to determine methanol content in non-wood pulping black liquor.The extraction and chromatopraphic conditions were optimized.The optimum conditions were as follows： 60℃ temperature for vapour-liquid equilibrium,30 min gas-liquid equilibrium time,11 min extraction time,280℃ desorption temperature,5 min desorption time.The method has good sensitivity and precision.
