摘要:

采用高效液相色谱法测定脱硫菌发酵液中2- 羟基联苯(2-HBP)的含量。以Delta-PakTM C18 (300A,3.9mm× 150mm,5μm)为色谱柱,甲醇:水(7:3,V/V)为流动相,流速1ml/min,用紫外检测器在260nm 处检测2-HBP。结果显示2-HBP 标准品的保留时间为2.6min,线性范围为0~80mg/L,利用该方法测得HDBRS-1 菌株发酵液中,2-HBP 的生成量为6.11mg/L。

关键词: 高效液相色谱法, 2-HBP, 检测

Abstract:

The concentration of 2-hydroxybiphenyl (2-HBP) in the fermentation broth of desulfurization strain was determined using HPLC. 2-HBP was separated thourgh a ODS column (3.9×150 mm, 5 μm, Delta-PakTM, Waters), eluted with 70% aqueous methanol at 1 ml/min, and detected at 260 nm. Results showed that retention time of 2-HBP was 2.6 min with the detection limits 0~80 mg/L and the 2-HBP concentration in the fermentation broth of strain HDBRS-1 was 6.11 mg/L.

Key words: HPLC, 2-HBP, detection
