The chemiluminescence (CL) of oxidation of non-steroidal anti-inflammatory drugs (NSAIDs) by Ce(IV) ions, was recorded in the presence and absence europium(III) ions, in solution of pH ~ 4 of solution. Kinetic curves and CL emission spectra of the all studied systems were discussed. CL of measurable intensity was observed in the Ce(IV)-NP-Eu(III) reaction system only in acidic solutions. The CL spectrum rcegistered for this system shows emission bands, typical of Eu(III) ions, with maximum at λ ~ 600 nm. The chemiluminescent method, based on Eu(III) emission in reaction system of NP-Ce(IV)-Eu(III) in acid solution was therefore used for the determination of naproxen in mixture of non-steroidal anti-inflammatory drugs.
铈(IV)离子氧化非甾体抗炎药(NSAIDs)的化学发光(CL),在存在和不存在铕(III)离子的情况下,在 pH ~ 4 的溶液中进行了记录。讨论了所有研究体系的动力学曲线和 CL 发射光谱。只有在酸性溶液中,Ce(IV)-NP-Eu(III)反应体系中才能观察到可测量强度的 CL。为该体系记录的 CL 光谱显示出铕(III)离子的典型发射带,最大发射波长在 λ ~ 600nm 处。因此,基于 NP-Ce(IV)-Eu(III)在酸性溶液反应体系中铕(III)发射的化学发光法被用于测定混合物中非甾体抗炎药中的萘普生。
