摘要: 采用HPLC方法, 以Symmetry 5 μm C18(4.6 mm×150 mm)为色谱柱, 0.002 0 mol/L的HSO4为流动相, 流速为1.0 mL/min, 采用 双波长紫外检测器,利用外标法测定糠醛废水中乙酸的含量. 此法检测的线性范围是0.040~0.400 g/L, r=0.999 8, 相对标准偏差RSD为0.536%(n=6), 实际样品的加标回收率为105.5%~115.7%.

Abstract: The high performance liquid chromatographic method was employed for determining the acetic acid (AC) in furfural waste water on a symmetry 5 μm C18 (4.6 mm×150  mm) column with 0.002 0 mol /L HSO4 as the mobile phase at a flow rate of 1.0 m L/min. The detection was made on a UV detector at 210 nm with external standard calibration. The liner operating range of the method is 0.040 0[KG-*4]~0.400 0 g/L(r=0.999 8) with a r elative standard division (RSD) of 0.536%(n=6). The average standard addition recovery of the wastewater samples is 105.5%[KG-*4]~115.7%.

Key words: acetic acid, high performance liquid chromatography, furfural wastewater
