Empirical Determination Of Rrde Collection Efficiency N

Once the collection efficiency value has been established empirically for a particular rrde, it can be treated as a property of that particular rrde, even if the rrde is used to study a different half reaction in a different solution on a different day. Adding a concentric ring allows the user to collect species that are produced on the disk in steady state mass transport–limited conditions. the maximum collection efficiency factor only depends on the geometry of the electrode. albery and bruckenstein [5] were the first to propose a theoretical expression to calculate . can be written. . For any given set of rrde dimensions (disk od, ring id, and ring od), the collection efficiency can be computed using formulae derived from fluid dynamics first principles. one useful aspect of the theoretical collection efficiency is that it is only a function of the rrde dimensions. Normally, for the commercially available rrde, the collection efficiency is in the range of 20–40% depending on the relative geometric sizes of the ring and disk electrodes. in addition, the collection efficiency is also dependent on the thickness of the isolator ring between the ring and disk electrodes ((r 2 − r 1) in figure 6.2). The autolab rrde electrode tips are fitted with a 5 mm electrode disc and a thin concentric platinum ring. the electrode disc is available in gold, platinum and glassy carbon. the rrde electrode tips are dimensioned with an electrode gap of 375 μm and a theoretical collection efficiency of 24.9 %.

For quantitative analysis the collection efficiency for the rrde geometry used must be known; this is the fraction of product pro duced at the disk that is detected at the ring. early theory of the rrde was developed by leveque and co workers.4,5albery6 and albery and bruckenstein,7 using boundary layer theory and apply. Rrde tip. the rrde tips have a theoretical collection efficiency of 24.9% based on the geometry of the disk and the ring. determination of the experimental collection efficiency and the meaning of the theoretical collection efficiency value are outside the scope of this application note. the counter.
