Guanine can quench the phthalhydrazidylazoacetylacetone's ECL in acid medium, and the linear concentration range of guanine relative to the ECL intensity is from 2.0×10~(-6) to 1.0×10~(-5) mol/L.The mechanism of phthalhydrazidylazoacetylacetone's ECL on the surface of ITO glass has been discussed according the experimental phenomenon.The phenomenon of ITO self-luminescence has also been studied.It has been found that the machanism of phthalhydrazidylazoacetylacetone on the surface of ITO in different medium is dissimilarity. The phenomenon of ITO self-luminescence may be caused by the interaction of the active oxygen element and ITO's surface.
