Herein, a fully biodegradable adsorbent was synthesized by the crosslinking reaction of \u03b2-cyclodextrin (\u03b2-CD) and chitosan via glutaraldehyde (CGC). The as-prepared CGC showed large adsorption capacities for gaseous formaldehyde. To clarify the adsorption performance of the as-synthesized HCHO adsorbents, changing the adsorption parameters performed various continuous flow adsorption tests. It was found that the adsorption data agreed best with the Freundlich isotherm, and the HCHO adsorption kinetic data fitted well with the pseudo second order model. The breakthrough curves indicated that the HCHO adsorbing capacity of CGC was up to 15.5 mg\/g, with the inlet HCHO concentration of 46.1 mg\/m3, GHSV of 28 mL\/min, and temperature of 20 \u00b0C. The regeneration and reusability of the adsorbent were evaluated and CGC was found to retain its adsorptive capacity after four cycles. The introduction of \u03b2-CD was a key factor for the satisfied HCHO adsorption performance of CGC. A plausible HCHO adsorption mechanism by CGC with the consideration of the synergistic effects of Schiff base reaction and the hydrogen bonding interaction was proposed based on in situ DRIFTS studies. The present study suggests that CGC is a promising adsorbent for the indoor formaldehyde treatment.<\/jats:p>","DOI":"10.3390\/polym11020276","type":"journal-article","created":{"date-parts":[[2019,2,6]],"date-time":"2019-02-06T11:51:12Z","timestamp":1549453872000},"page":"276","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":43,"title":["Enhanced Formaldehyde Removal from Air Using Fully Biodegradable Chitosan Grafted \u03b2-Cyclodextrin Adsorbent with Weak Chemical Interaction"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2319-3055","authenticated-orcid":false,"given":"Zujin","family":"Yang","sequence":"first","affiliation":[{"name":"School of Chemical Engineering and Technology, Sun Yat-sen University, Zhuhai 519082, China"},{"name":"Huizhou Research Institute of Sun Yat-sen University, Huizhou 516216, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongchen","family":"Miao","sequence":"additional","affiliation":[{"name":"Fine Chemical Industry Research Institute, The Key Laboratory of Low-carbon Chemistry &amp; Energy Conservation of Guangdong Province, School of Chemistry, Sun Yat-sen University, Guangzhou 510275, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zebao","family":"Rui","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering and Technology, Sun Yat-sen University, Zhuhai 519082, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongbing","family":"Ji","sequence":"additional","affiliation":[{"name":"Huizhou Research Institute of Sun Yat-sen University, Huizhou 516216, China"},{"name":"Fine Chemical Industry Research Institute, The Key Laboratory of Low-carbon Chemistry &amp; Energy Conservation of Guangdong Province, School of Chemistry, Sun Yat-sen University, Guangzhou 510275, China"},{"name":"School of Chemical Engineering, Guangdong University of Petrochemical Technology, Maoming 525000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,2,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"9928","DOI":"10.1021\/es4019892","article-title":"NaOH-modified ceramic honeycomb with enhanced formaldehyde adsorption and removal performance","volume":"47","author":"Yu","year":"2013","journal-title":"Environ.
