Absorption of SO2 into aqueous systems

Glassy Carbon Electrode Modified with Functionalized Carbon Nanotubes Within a Poly(allylamine hydrochloride) Film for the Voltammetric Determination of Sulfite in Foods

“…As reported in the literature [39] , the sulfite when dissolved in aqueous solution exists in three forms depending on the pH values and, may be present in molecular form, SO 2 , or in ionized state, according to the equilibria (Equations 1-3 , as shown in Figure 5. The oxidation peak for sulfite in an acetate buffer solution (pH 4.6) shifted slightly toward more positive potentials as scan rate increased, a typical characteristic of irreversible electrochemical reactions.…”

Prediction of the Removal Efficiency of a Novel Two‐Stage Hybrid Scrubber for Flue Gas Desulfurization

“…A legion of processes and methods were discussed therein, and wet scrubbing with NaOH solutions seemed promising amongst many other options. Bronikowska and Rudzinski [9] proposed models for the absorption of SO 2 into aqueous solutions containing sulfites based on the film theory of gas absorption and the chemical equilibrium treatment of chemical reactions. Schmidt and Stichlmair [10] investigated mass transfer in co-current spray scrubbers.…”

Equilibria in a Limestone Based FGD Process: A Pure System and with Chloride Addition

“…In the case of pure substances, these data are widely accessible in the literature but the information concerning ions and ion pairs is rather poor and fragmented [12]. The second method is based on the simultaneous solution of equations describing the equilibrium constants of every species present in the system, and mass and charge balances [3,5]. The relationships describing the dependencies of dissociation constants and Henry's constants on temperature are widely available [13].…”
