「摘要]建立了一种可同时测定苯酚生产废水中苯、甲苯、异丙苯、苯酚、甲基苯甲醇、2-苯基-2ー内醇、苯乙制、2-苯基丙
醛和2-苯基-1-丙烯等9种物质的HPLC分析方法。考察了检测波长、流动相配比、流动相流量和柱温等条件对分析结果的影
响。实验结果表明,最佳色谱条件为:检测波长210nm,流动相为(乙腈):(水)=65:35,流量1.0mL/min,柱温35℃。
在质量浓度0.05~120.00mg/L内,各物质的标准工作曲线具有良好的线性关系,相关系数大于等于0.9997,相对标准偏差小
于2%(n=7),各物质的最低检出限为0.005~0.009mgL,加标回收率为95.0%~105.3%。该方法预处理简单、分析时间短、
灵敏度高,可用于苯酚生产废水中苯系物及其衍生物含量的快速检测。

I Abstract A HPLC method was established to determine the contents of benzene
toluene, cumene, phenol, Dl-1-phenethylalcohol, 2-phenyl-2-propanol, acetophenone
2-phenylpropionaldehyde and 2-phenyl-1-propene in wastewater from phenol production. The influences
of wavelength, volume ratio of mobile phase, flowrate and column temperature were investigated
The results indicate that the optimal chromatographic conditions are detection wavelength 210 nm
V(acetonitrile): (water)65: 5 as the mobile phase, flowrate 1.0 ML/min and column temperature
35 C Under the conditions, in the mass concentration range of.05-12000 mg/L, the standard work
curves of the compounds have good linear relationship, the correlation coefficients are more than or
equal to 0.999 7, the relative standard deviations are less than 20(=7) the minimum determination
limits are in the range of 0.005-0.009 m / L and the average recoveries are in the range of 95.0%-105.3%
This method has the features of simple pretreatment, short analysis time and high sensitivity, and can
be used to rapidly detect the contents of benzene series and derivatives in the wastewater
