Evaluation of Diffusion Coefficients of Small Ions in a Microfluidic Channel

  • Published:
Bulletin of the Russian Academy of Sciences: Physics Aims and scope

Abstract

In this paper, we analyze reaction processes that occur in laminar flows of a flow focusing microfluidic device. The microfluidic reaction systems that comprise hydroxonium and hydroxyl ions are proposed as the media for evaluating diffusion coefficients of reacting particles. Diffusion coefficients are calculated by comparing the experimental data with the results of mathematical simulations. The diffusion coefficients evaluated with microfluidic chip agree well with the literature data.
