摘　　要：在碱性环境下,对苯二酚对鲁米诺-高碘酸钾体系产生的化学发光有很强的增敏作用,基于此体系,建立了测定对苯二酚的流动注射化学发光法。该方法简单、方便、灵敏度高。测定的检出限为8.2×10-10molL,线性范围为8.0×10-9～1.0×10-6molL,对浓度为5.0×10-7molL的对苯二酚进行11次平行测定,相对标准偏差为0.85%。用该法测定废水中对苯二酚的含量,结果令人满意。Under basic condition, hydroquinone has strong sensitivity enhancement ability to chemiluminescence produced by luminol-KIO4 system. Based on this system, a flow injection-chemiluminescence method has been established for the determination of hydroquinone. The method is simple, convenient and sensitive. The linear range is 8.0×10^-9-1.0×10^-6 mol/L with the detection limit of 8. 2 ×10^-10 mol/L. The RSD is 0.85% for 5.0 × 10^-7mol/L hydroquinone （n = 11）. The method has been used for the determination of hydroquinone in waste water with satisfactory results.
