Abstract

Chemiluminescence CL of selected inorganic reaction systems, generating ultraweak photonemission, has been studied. The kinetics of the systems and their emission spectra have been characterisedby measurements with the use of the stationary and the flow methods of CL recording. The systems studiedcontained cations at different oxidation degree such as Fe2+\3+, Cu+\2+, Co2+\3+, Eu2+\3+, CLO− anions and hydrogen peroxide without organic sensitisers. On the basis of the analysis of the spectra, in particularsystems emitters have been identified and mechanisms of the reactions have been proposed. The effectof carbonate and azide ions and propylene carbonate on the yield of CL and spectral characterisationof the systems studied has been evidenced and discussed. A possibility of the application of the systems Eu3+\N3− \H2O2 and Co2+\propylene carbonate\H2O2 for analytical purposes has been considered.
