Chemiluminescence System of Ce(Ⅳ)-RhB-Bismerthiazol
Abstract:
A novel chemiluminescence system for the determination of bismerthiazol is described in this paper.It is based on the chemiluminescence reaction of bismerthiazol and Ce(Ⅳ) in nitric acid solution.The emission intensity can be enhanced greatly by Rhodamine B.The chemiluminescence intensity was propor-tional to bismerthiazol concentration over a range of 30~1 000 μg/L.The detection limit was 12 μg/L(3σ) and the relative standard deviation was 2.4% for 500 μg/L bismerthiazol (n=11).The proposed method was successfully applied to the determination of bismerthiazol in water and in rice.The recovery was 96.4%~104.1%.
