SO2is an acidic gas, and when it reacts with the basic solution of calcium hydroxide in limewater, it neutralizes the base and forms a salt (calcium sulfite) and water. This reaction is often used as a test for the presence of SO2 gas. When SO2 is bubbled through limewater, the ...
On the surface of the packing, the gas-liquid two phases fully contact, absorb and neutralize the reaction, and adsorb the acidic or basic pollutants contained in the exhaust gas. After the acid mist exhaust gas is purified, the clean gas is dehydrated and defogged by the demister ...
This paper summarises basic studies on the mechanism of SO 2/O 2 oxidation, the kinetics of oxidation in acidic media, and potential applications in hydrometallurgy. The SO 2/O 2 system readily oxidises Fe(II) to Fe(III) and provides a simple method of regenerating Fe(III) for leaching ...
Compared with conventional acidic oxide carriers such as TiO2, it is easier to adsorb acid reaction molecules SO2, which is conducive to the adsorption and activation of reaction molecules, thereby improving the catalytic activity. According to the Tanabe rule, the coordination charge number of ...
Detection of an acidic (CO2, SO2) or basic (NH3) gas by monitoring a dielectric relaxation of a reaction product (for example of a zwitterion) of an acid-base reaction of the gas with a chemical compound (like DBU) using an integrated circuit...

Oxidation of the ACFs, using an aqueous oxidant, decreased their adsorption capacity for SO2 from flue gas due to a decrease in pore volume and repulsion of the SO2 from acidic surface groups. If these samples were heat-treated to desorb the oxygen containing function groups, the amount of SO...
