The oxidant is the oxygen in flue gas. The couple of cobalt recycle and I〓 recycle realized by photocatalysis keeps the active constituent-hexamminecobalt ions constant. The oxidation and absorption of nitric oxide can be carried out simultaneously, so is the absorption and oxidation of sulfur dioxide. Nitric oxide removal may be over eighty percent at the concentration between 250ppm and 800ppm and sulfur dioxide removal is 100 percent at the concentration between 800ppm and 2500ppm. Such method is superior to hydrogen peroxide and Fe -EDTA.
