摘要
采用高效液相色谱法同时测定废水中间苯二酚和对苯二酚的含量,以酚类化合物浓度为横坐标,峰面积为纵坐标,绘制标准曲线,通过精密度试验、稳定性试验以及加标回收率实验对该方法进行评价。结果表明:测定间苯二酚的线性回归方程为Y=0.00009X+0.31783,测定对苯二酚的线性回归方程为Y=0.0002X-1.36472。在设定的色谱条件下,模拟废水中间苯二酚浓度为6.27 mg/L,对苯二酚浓度为2.30 mg/L,加标回收率试验、精密度试验和稳定性试验结果表明,该检测方法准确可靠。
HPLC was employed to determine the contents of resorcinol and hydroquinone simultaneous, the standard curves were used to determine the content of hydroquinone and resorcinol in wastewater, and the method was evaluated by recovery rate test, precision test and stability test. The results indicated that the linear equation of resorcinol was Y=0.00009 X+0.31783 and the linear equation of hydroquinone was Y=0.0002 X-1.3647. The linear correlation was good. The concentration of resorcinol in wastewater was 6.27 mg/L, and the concentration of hydroquinone was 2.30 mg/L, the results of recovery rate test, precision test and stability test showed that this method was accurate and reliable.
