Cupric ions, which have a high complexing ability toward HCN, were introduced to the CMC\/CA composite microspheres during the fabrication process via an in situ ion cross-link method. The microspheres were characterized using nitrogen adsorption, mercury intrusion porosimetry, and scanning electron microscopy (SEM). The microspheres have a predominantly macroporous structure indicating weak physisorption properties, but sufficient functional cupric ion groups to selectively adsorb HCN. With these CMC\/CA microspheres as filter additives, the smoke yield of HCN could be reduced up to 50%, indicating the great potential of these microspheres as absorbents for removing HCN from cigarette smoke.<\/jats:p>","DOI":"10.3390\/polym11010181","type":"journal-article","created":{"date-parts":[[2019,1,22]],"date-time":"2019-01-22T03:08:22Z","timestamp":1548126502000},"page":"181","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Functional Porous Carboxymethyl Cellulose\/Cellulose Acetate Composite Microspheres: Preparation, Characterization, and Application in the Effective Removal of HCN from Cigarette Smoke"],"prefix":"10.3390","volume":"11","author":[{"given":"Peijian","family":"Sun","sequence":"first","affiliation":[{"name":"Zhengzhou Tobacco Research Institute of CNTC (China National Tobacco Corporation), Zhengzhou 450001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Song","family":"Yang","sequence":"additional","affiliation":[{"name":"Zhengzhou Tobacco Research Institute of CNTC (China National Tobacco Corporation), Zhengzhou 450001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuehui","family":"Sun","sequence":"additional","affiliation":[{"name":"Zhengzhou Tobacco Research Institute of CNTC (China National Tobacco Corporation), Zhengzhou 450001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yipeng","family":"Wang","sequence":"additional","affiliation":[{"name":"Zhengzhou Tobacco Research Institute of CNTC (China National Tobacco Corporation), Zhengzhou 450001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lining","family":"Pan","sequence":"additional","affiliation":[{"name":"Zhengzhou Tobacco Research Institute of CNTC (China National Tobacco Corporation), Zhengzhou 450001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongbo","family":"Wang","sequence":"additional","affiliation":[{"name":"Zhengzhou Tobacco Research Institute of CNTC (China National Tobacco Corporation), Zhengzhou 450001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoyu","family":"Wang","sequence":"additional","affiliation":[{"name":"Zhengzhou Tobacco Research Institute of CNTC (China National Tobacco Corporation), Zhengzhou 450001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jizhao","family":"Guo","sequence":"additional","affiliation":[{"name":"Zhengzhou Tobacco Research Institute of CNTC (China National Tobacco Corporation), Zhengzhou 450001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cong","family":"Nie","sequence":"additional","affiliation":[{"name":"Zhengzhou Tobacco Research Institute of CNTC (China National Tobacco Corporation), Zhengzhou 450001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,1,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Rodgman, A., and Perfetti, T.A.
