Abstract
Tartaric acid solution is applied to change the surface characteristics of activated carbon to improve its catalytic capability in the regeneration of Co(NH3)62+ that is used to realize the simultaneous removal of NO and SO2. The experimental results show that the best treatment condition is impregnating the carbon samples in 1.5 mol l−1 tartaric acid solution for 18 h followed by being activated at 400°C for 4 h under nitrogen atmosphere. After being treated with tartaric acid solution, the surface area of activated carbon and the acidity on its surface increase. The experiments show that the modified carbon can obtain a much higher NO removal efficiency than the original carbon. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 333–341, 2018
