摘要
基于高铁酸盐可以氧化鲁米诺发光的特性,建立了一种新型、快速、环境友好的在线监测高铁酸盐稳定性的方法———流动注射—化学发光分析法。研究了温度、溶液pH值、添加剂对高铁酸盐稳定性的影响,结果表明,低温和高碱度是保持高铁酸盐溶液稳定的关键因素,硅酸钠作为添加剂有助于提高高铁酸盐的产率和稳定性。
Based on the homogeneous chemiluminescence(CL) reaction of Luminol oxidized by ferrate(Ⅵ),a novel,convenient,environmental friendly,on-line monitoring method was established to investigate the stability of ferrate(Ⅵ) solution.The effects of temperature,pH value,additive on the stability of ferrate(Ⅵ) solution were traced by flow injection-chemiluminescence analysis method.The results showed that low storage temperature and high pH value were the key factors for keeping the stability of ferrate(Ⅵ) solution,and Na2SiO3 could effectively enhance the yield and the stability of ferrate(Ⅵ) solution.
