O processo da eletrorredução de benzodiazepinas, uma ferramenta, capaz de usar-se em pesquisa eletroanalítica, foi analisado dos pontos de vista mecanístico e matemático.
O modelo correspondente veio sendo investigado por meio de teoria de estabilidade linear e análise de bifurcações e, por meio da sua análise, pôde-se obter o requisito da melhor eficiência do processo, investigar a pH-dependência do seu desempenho, bem como as condições das instabilidades oscilatória e monotónica.
Faz-se uma tentativa de uma análise mecanística sistemática do desempenho de sensores eletroquímicos de benzodiazepinas.
The benzodiazepines' electrochemical reduction process, a tool, capable to be used in electroanalytic investigation, was anaylzed by mechanistic and mathematical means. The correspondent model was analyzed by means of linear stability theory and bifurcation analysis, and by its mean it was possible to get the requisite for the best process efficiency, the pH-dependence of its function, like also of oscillatory and monotonic instability. An effort is made fot the systematic mechanistic analysis of the work of benzodiazepine electrochemical sensors.
