Chemiluminescence (CL) of selected inorganic reaction systems, generating ultraweak photon emission, has been studied. The kinetics of the systems and their emission spectra have been characterised by measurements with the use of the stationary and the flow methods of CL recording. The systems studied contained 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 particular systems emitters have been identified and mechanisms of the reactions have been proposed. The effect of carbonate and azide ions and propylene carbonate on the yield of CL and spectral characterisation of 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.
