气相色谱法测定废水中光引发剂1103

Determination Photo Initiator 1103 in Wastewater by Gas Chromatography

建立了化工废水中光引发剂1103的气相分析方法.废水经甲苯萃取后,采用HP-5（30 m×320 μm×1.80 μm）毛细管柱气相分离,FID检测器测定含量,用保留时间定性,外标法定量,光引发剂1103的浓度与其对应的峰面积之间的线性关系良好.该方法结果线性范围为100～1000mg/L,相对标准偏差为0.89％,平均加标回收率为96.4％.

An analysis method for the determination of photo initiator 1103 in chemical wastewater was established by gas chromatography. Wastewater treatment by toluene extraction, using HP-5 （30 m×320 μm× 1.80 μm） capillary column gas phase separation, determination of the content of FID detector, with retention time qualitative, quantified by external standard method, the linear relationship between the peak area of compound concentration corresponding to the good. This method results in the range of 100-1000 mg/L, the relative standard deviation is 0.89 %, the average recovery is 96.4 %.
