摘要
通过实验建立了工业废水中盐酸苯肼的高效液相色谱分析方法。色谱条件为:Kromasil-C18(150 mm×4.6 mm,5μm)色谱柱,流速1 mL/min,柱温30℃,进样体积10μL,流动相为V(甲醇)∶V(8 mmol/L KH2PO4+4 mmol/LK2HPO4)=35∶65,测定波长235 nm。测定结果表明,线性范围为0.1～100 mg/L,平均加标回收率为98.2%,相对标准偏差为1.06%。该方法操作简单,分析快速、准确。
The HPLC method for determining phenylhydrazine hydrochloride in industrial wastewater has been established. The chromatogram conditions are as follows ： Kromasil-C18 column （150 mmx 4.6 mm, 5μm）, velocity of flow 1 mL/min,column temperature 30℃,sample volume 10μL,mobile phase is V（methanol）：V（8 mmol/L KH2PO4 ＋ 4 mmol/L K2HP04） =35 ：65 ,and wavelength 235 nm. The results show that the method offeres good linearity from 0.1-100 mg/L, average recovery rate is 98.2% and RSD 1.06%. This method is characterized by easy operation, and rapid and accurate analysis.
