摘要：

We investigated NOx removal using a CO3 center dot Mg-Al layered double hydroxide (CO3 center dot Mg-Al LDH) and compared its NO2 removal performance against that of Mg(OH)(2) and NO3 center dot Mg-Al LDH to elucidate the nature of adsorption of NO2 center dot The NO removal rate was lower than that for NO2 removal. The success of NO2 removal with CO3 center dot Mg-Al LDH is attributed to the surface adsorption of NO2 on CO3 center dot Mg-Al LDH in addition to the formation of NOx center dot Mg-Al LDH. We investigated its recycling in NO2 treatment by CO3 center dot Mg-Al LDH. The results demonstrated the possibility of recycling through CO3 center dot Mg-Al LDH generation using a Na2CO3 solution.
