Organic electrode reactions, rate constant calculation

In the presence of substances that react with Ag , the 340 nm absorption decays more rapidly and the rate constant of reaction can be calculated from this decay. It was found in this way that free silver atoms are indeed a strongly reducing species. They reduce Fe to Fe and Cu to Cu (note that these reactions would not occur with the silver atoms at the surface of a compact electrode ) organic compounds containing electrophilic groups such as CICH2COOH or CH3NO2 are reduced by Ag via electron transfer... 

The fast complexation rate of Zn(II) ion with 8-quinolinol (Hqn) or 5-octyloxymethyl-8-quinolinol (Hoeqn) at the 1-butanol/water interface was measured by the micro-two-phase sheath flow method [17], The formation of a fluorescence complex at the interface was measured within a period of less than 2 milliseconds after the contact of the two phases. The depth profile of the fluorescence intensity observed across the inner organic phase flow proved that the fluorescence complex was formed only at the interface and it increased in proportion to the contact time. The diflusion length of Hoeqn in the 1-butanol phase for 2 milliseconds was calculated as 0.8 pm, which is smaller than the experimental resolution depth of 2 pm in the microscopy used. Therefore, the observed rate constant was analysed by taking diffusion and reaction rates into account between Zn(II) and Hoeqn at the interfacial region by a digital simulation method. The digital simulation has been used in the analysis of electrode reactions,...
