Based on the chemiluminescence (CL) phenomenon of peroxymonosulfate (PMS) and Tb(III) enhanced by its ligand in a micelle microenvironment, a fast and sensitive flow injection CL method for PMS detection was proposed and applied to the analysis of different samples and PMS decomposition. Under the optimized conditions, a linear range was obtained from 4.0 × 10-6 mol L-1 to 2.0 × 10-4 mol L-1 with a high correlation coefficient (r = 0.9997), detection limit of 5.0 × 10-7 mol L-1 (S/N = 3) and relative standard deviation of 2.4% for 1.0 × 10-5 mol L-1 PMS (n = 9). This was successfully applied to the determination of PMS in Virkon powder, tap water, and swimming pool water samples with satisfactory recoveries from 94.8% to 104.8%. In particular, the analytical frequency could be as fast as five samples per minute because there was no reaction step before analysis and the CL phenomenon was instantaneous. Therefore, this CL method has also been successfully applied to investigate the PMS decomposition profiles in carbon material (carbon nanotubes, carbon nanofibres, activated carbon and graphene oxide) catalysis systems, which followed pseudo-first-order kinetics with good correlation coefficients (r > 0.9305). Quenching experiments and electron spin resonance spectra verified that the CL phenomenon was due to the formation of singlet oxygen, and that hydroxyl and sulfate radicals might be important in the generation of singlet oxygen. Tb(III) is the luminescent emitter according to the characteristics emission bands of the fluorescence and CL spectra in different media.

使用胶束培养基中的Tb（III）配体通过流动注射化学发光法快速测定过氧单硫酸盐。

基于胶束微环境中配体增强的过氧单硫酸盐（PMS）和Tb（III）的化学发光（CL）现象，提出了一种快速灵敏的流动注射CL法检测PMS，并将其应用于不同样品和PMS的分析中分解。在最佳条件下，线性范围从4.0×10-6 mol L-1到2.0×10-4 mol L-1，具有较高的相关系数（r = 0.9997），检出限为5.0×10-7 mol L-1（S / N = 3）和1.0×10-5 mol L-1 PMS（n = 9）的相对标准偏差为2.4％。该方法成功地用于测定Virkon粉末，自来水和游泳池水样品中的PMS，回收率从94.8％至104.8％，令人满意。特别是，分析频率可能高达每分钟5个样品，因为分析之前没有任何反应步骤，并且CL现象是瞬时的。因此，该CL方法也已成功地用于研究碳材料（碳纳米管，碳纳米纤维，活性炭和氧化石墨烯）催化系统中的PMS分解曲线，其遵循具有良好相关系数的拟一阶动力学（r> 0.9305）。淬火实验和电子自旋共振谱证明，CL现象是由于单线态氧的形成所致，并且羟基和硫酸根自由基可能在单线态氧的产生中起重要作用。根据不同介质中荧光和CL光谱的特征发射带，Tb（III）是发光体。
