A green and low toxicity polymer nanoparticles in chemiluminescence behavior of peroxyoxalate and hydrogen peroxide

以组氨酸为碳源,制备一种绿色低毒的聚合物纳米粒子(PNPs),并研究其在过氧草酸酯-过氧化氢(TCPO-H2O2)体系中的化学发光行为。结果表明,PNPs对该化学发光体系有明显的增强作用。进一步探讨H2O2、TCPO、PNPs浓度以及流速条件对体系的影响,并通过对该聚合物纳米粒子的表征以及化学发光动力学的讨论,探究PNPs-TCPO-H2O2化学发光体系可能的发光机理,为建立新型过氧草酸酯类物质的化学发光体系开拓了新的思路。

Histidine,as carbon source,has been successfully employed to synthesize a green,low toxicity polymer nanoparticles(PNPs).The results show that PNPs have an enhanced effect on chemiluminescence behavior of the bis(2,4,6-Trichlorophyenyl)oxalate(TCPO)and hydrogen peroxide system.We discussed the effects of hydrogen peroxide concentration,TCPO concentration,PNPs concentration and flow rate conditions on the system.After the discussion of the characterization of the PNPs and the chemiluminescence kinetic properties,the possible mechanism of the system is explored,which develops a new method for chemiluminescence of peroxyoxalate.
