摘要
采用流动注射技术研究了酸性条件下 ,高锰酸钾与对苯二酚的化学发光行为 ,对影响化学发光强度的诸因素进行了试验和探讨 ,建立了流动注射化学发光法测定对苯二酚的新方法。方法的检出限为 6× 10 - 8g·ml- 1,线性范围为 2 .0× 10 - 78.0× 10 - 5g·ml- 1,对 4 .0× 10 - 6 g·ml- 1对苯二酚进行 11次平行测定 ,相对标准偏差为 1.5 %。方法用于测定废水中对苯二酚的含量 ,结果满意。
The chemiluminescence behavior of the oxidation reaction of hydroquinone (HQN) by potassium permanganate was studied under the condition of flow-injection. The intensity of chemiluminescence was found to be in linear relationship with the concentration of hydroquinone in the range of 2.0×10 -7 to 8.0×10 -5 g·ml -1 . The precision was tested at the concentration level of 4.0×10 -6 g·ml -1 for 11 determinations and the value of RSD obtained was 1.5%. This proposed method has been used satisfactorily in the determination of hydroquinone in waste water.
