Regarding the issue of activated carbon adsorption
Thread Content
The flue gas contains acidic gases such as sulfur dioxide, hydrogen chloride, and hydrogen sulfide. If activated carbon is chosen as the filler and this activated carbon is continuously washed with a weakly alkaline solution of sodium bicarbonate, will it still have adsorption capabilities? Or how effective is it?
Yes, but the adsorption capacity decreases! Generally, activated carbon has a higher adsorption rate in acidic solutions than in alkaline solutions
