2) is supposed to take place in the 2,4-xylidine degradation process; the first step for xylidine oxidation is probably just the formation of nitroaromatics.
The adsorption isoterms, xylidine diffusion coefficient in GAC pores, and breakthrough curves are presented in .
The reaction rate of xylidine is a function of the concentrations of the reacting species on the surface of the GAC.
The fuel consists of triethylamine (50 wt%) and xylidines or dimethylanilines (45 wt%) .
Several investigations have been carried out on the purification of water contaminated with aromatic amines, including xylidines. Some of them are presented in our previous study .
Triethylamine is an easily volatile component and therefore the treatment of xylidine, as the main toxic component, was in the focus of this work.
Because of low concentration of xylidine in groundwater, the effectiveness of the biodegradation process is questionable.
A possible explanation is that the xylidine adsorption equilibrium follows the Freundlich isotherm while the Rice method uses the linear isotherm and the Thomas method uses the Langmuir isotherm equation.
