We conducted a one-dimensional reaction–diffusion simulation to model methylene blue (MB) decomposition using a microplasma contactor. To account for the experimental results, an increase in the effective transport coefficients of chemical species in the liquid was required, suggesting contributions beyond diffusion. Furthermore, by independently and virtually varying the transport coefficients of individual liquid-phase species, we found that improving the transport efficiency of the target species, MB, toward the interface is critically important for enhancing the overall processing efficiency.
