Modeling of the chemical composition of dc atmospheric pressure air discharge plasma in contact with aqueous solutions of sodium dodecylbenzenesulfonate
Abstract:
The results of calculation of the chemical composition of plasma of the DC atmospheric pressure discharge in air in contact with aqueous solutions of sulfonol $(\rm C_{12}H_{25}C_6H_4SO_3Na)$ in the concentration range of $0$–$10$ g/L at a discharge current of $40$ mA are presented. At modeling, the combined solution of Boltzmann equation for the electron gas, equations of vibrational kinetics for ground states of $\rm N_2$, $\rm O_2$, $\rm H_2O$ and $\rm NO$ molecules, equations of chemical kinetics and plasma conductivity equation were used. It was shown that sodium atoms appearing as a result of transfer processes from the liquid cathode affect the chemical composition of the plasma and the characteristics of the electron gas.
