| pubmed-article:20800264 | pubmed:abstractText | It is important to treat gaseous HCl from incineration streams efficiently to avoid adverse environmental consequences. In this paper, a new treatment method for gaseous HCl is presented-the application of Mg-Al layered double hydroxide (LDH) intercalated with CO(3)(2-) (CO(3)·Mg-Al LDH) to treat gaseous HCl continuously. The degree of HCl removal without water vapor is higher than that with water vapor; further, this reaction does not require H(2)O. In addition, the degree of HCl removal increases with increasing temperature, CO(3)·Mg-Al LDH quantity, HCl concentration, and improved contact between CO(3)·Mg-Al LDH and HCl gas. The treatment of HCl gas by CO(3)·Mg-Al LDH leads to the production of Mg-Al LDH intercalated with Cl(-). Further, HCl is also absorbed on the surface of CO(3)·Mg-Al LDH. Our proposed treatment method works effectively for the treatment of gaseous HCl from incinerator streams. | lld:pubmed |
