摘要: C1O--H2O2可强烈氧化某些有机物而发光,碱性介质中的异丙醇也可被ClO--H2O2氧化产生化学发光,乙醛的存在可显著增强该体系的化学发光效果,且被敏化的化学发光强度与一定范围内的乙醛浓度有良好的线性关系,依据上述关系,我们建立了用于测定痕量乙醛的新方法,该法具有较高的灵敏度,检出限为1.0×10-10g/mL乙醛,线性响应范围大于3个数量级,将此法应用于测定有机化工厂废水中的乙醛,结果满意。

Abstract: The chemilluminescent reaction of iso-propyl alcohol with ClO--H2O2which is enhanced by acetaldehyde is reported. Based on this chemiluminescent reaction, a new method for the determination of trace acetaldehyde is developed. The detection limit is 1. 0×10-10g/mL acetaldehyde and the linear dynamic range is more than three orders of magnitude. The method has been satisfactorily applied to the determination of trace acetaldehyde in waste water samples of organic chemical plant.
