中文摘要：

基于中性介质中，2，4-二氯苯酚对鲁米诺-铁氰化钾化学发光体系有明显的增敏作用，提出了流动注射化学发光法测定痕量2，4-二氯苯酚的方法．在优化的试验条件下，2，4-二氯苯酚的化学发光强度与其浓度在1．0×10^-7～1．0×10^-5mol／L范围内呈线性关系，方法的检出限（3S／N）为1．060×10^-8mol／L．对浓度为1．0×10^-5mol／L 2，4-二氯苯酚溶液连续测定11次，测定值的相对标准偏差为2．1％．取工业废水水样，经固相萃取后用该法测定其中痕量2，4-二氯苯酚含量，同行业推荐标准方法对比，结果相近．

英文摘要：

Based on the chemiluminescence （CL） reaction of oxidation （potassium ferricyanide） and the chemiluminescent （Luminol）, 2,4-Dichlorophenol can enhanced the reaction, a FI-CL method for determination of trace amounts of catechol was proposed. Under optimum conditions, linear relationship between values of CL intensity and concentration of 2,4-Dichlorophenol was obtained in the range of 1.0×10^-7- 1.0 ×10^-5 mol/L, with detection limit（3S/N） of 1. 060×10^-8 mul/L. Precision of the method was tested at the concentration level of 1.0）〈 10 s mol/L of 2,4-Dichlorophenol, for 11 determinations, value of RSD found was 2.1%, 2,4-Dichlorophenol in samples of waste water was purified by solid phase extraction, and determined by the proposed method.
