摘　　要：建立高效液相色谱法快速测定过氧化氢工作液中2-乙基蒽醌、2-戊基蒽醌及其氢化物含量的方法。选择ZorbaxXDB–C_(18)色谱柱(250 mm×4.6 mm,5μm)为分离柱,以甲醇–水溶液(体积比为75∶25)为流动相,流量为0.8 mL/min,柱温为40℃,紫外检测器检测,检测波长为254 nm,外标法定量。2-乙基蒽醌、2-戊基蒽醌及其氢化物在各自的质量浓度范围内与色谱峰面积具有良好的线性关系,相关系数均大于0.999,检出限为0.012~0.035 mg/L。测定结果的相对标准偏差为0.35%~3.60%(n=6),样品加标回收率为98.5%~106.9%。该方法操作简单,精密度和准确度高,适用于工业生产中批量快速检测。A rapid method for the determination of 2-ethylanthraquinone,2-pentylanthraquinone and their hydrides content in hydrogen peroxide working-solution by high performance liquid chromatography was established.Zorbax xdb-C_(18) column(250 mm×4.6 mm,5μm)was used as the separation column,methanol–water solution(volume ratio was 75∶25)was used as mobile phase with the flow rate of 0.8 mL/min,column temperature was 40℃,UV detector detection,detection wavelength was 254 nm,and external standard method was used for quantitative analysis.The mass concentrations of 2-ethylanthraquinone,2-pentylanthraquinone and their hydrides had a good linear relationship with the chromatographic peak area in their respective ranges,the correlation coefficients were all more than 0.999,and the detection limits were 0.012–0.035 mg/L.The relative standard deviations of the determination results were 0.35%–3.60%(n=6),and the recoveries were 98.5%–106.9%.The method is easy to operate with high precision and accuracy,which is suitable for batch rapid detection in industrial production.
