摘　　要：采用H2O2处理生物丁醇样品，并以离子色谱抑制电导法检测其中CI-等无机阴离子的浓度，检出限为0．5～2．0μg／L（S／N=3），回收率为96．8％-102．2％，重现性范围为0．59％-0．84％。该法可于14min内完成，操作快速，无丁醇基体干扰，灵敏度高，重现性好。After H2O2 treatment, Cl- and some inorganic anions in butanol sample were determined by ion chromatography with suppressed conductivity detection. The detection limits （ S/N=3 ）, recovery and reproducibility were in the range of 0.5-2.0 μg/L, 96.8%-102.2% and 0.59%-0.84%, respectively. The analytical period is short （in 14 min）, and the method showed no butanol matrix interference, higher sensitivity, and good reproducibility.
