| 摘 要： | 依据邻、间、对氯硝基苯三组分的比值光谱特征，以间氟硝基苯为参比组分，选择219nm、232nm和244nm、297nm作为邻氯硝基苯和对氯硝基苯的测定波长；以对氯硝基苯为参比组分．选择253nm、325nm作为间氟硝基苯的测定波长．测定邻、间、对氯硝基苯混合样品中三组分含量，结果显示。邻氯硝基苯在（3．73～74．34）mg／L，间氯硝基苯在（1．58～105．1）mg／L，对氯硝基苯在（0．36-107．1）mg／L范围具有良好的线性关系．回收率均在95．0％～110．0％之间．本法具有测定波长少、计算简单、光谱“分离”能力强。易于推广等特点．

| Abstract: | Taking m-Chloronitrobenzene as disturbance component, the wavelengths of 219 nm, 232 nm and 244 nm, 297 nm were chosen as the determination of the o-Chloronitrobenzene and p-Chloronitrobenzene respectively. And if taking the p-Chloronitrobenzene as disturbance component, the 253 nm and 325 nm were chosen as the determination of the m-Chloronitrobenzene. It is shown that good linear corre- lations exit for o-Chloronitrobenzene（7.43-74. 34） mg/L, m-Chloronitrobenz.ene （3.15- 105. 1） mg/L and p-Chloronitrobenzene（0.36-107. 121） mg/L. The recoveries were 95.0%- 110.0% . The method is simple and practical with fewer determination wavelengths and powerful spectral resolution, and is easy to spread for application. |
