A Study on Gadolinium Sensitized Chemiluminescence System

Abstract:

A new chemiluminescence system was built by using gadolinium as sensitizer, and the analysis capabilities of this system was tested as below. The method is based on chemluminescence of Ce (IV)-SO₃^2- sensitized by Gd³⁺-OFLX. The effects of some critical experimental conditions were discussed and the optimum conditions for chemluminescence emission were investigated. The linear relationship between the relative chemiluminescence intensity and the concentration of OFLX is in the range of 2×10^-9 g/mL～5×10^-7 g/mL with a detection limit of 1.0×10^-9g/mL .The relative standard deviation is 2.8% (n=11) for a level of 5.0×10^-7 g/mL. The method has been applied to the analysis of OFLX in tablets with satisfactory results.
