The preparation process mainly included two steps: load-alkali leaching and chemical activation. The porosity characteristics (specific surface area and mesopore ratio) were controlled by changing the K2CO3 impregnation ratio, activation temperature, and Fe3+ ions loading during the activation process. Additionally, three FBPC samples with different pore structures and characteristics were studied for copper adsorption. The results indicate that the adsorption performance of the bamboo powder biochar FBPC material was greatly affected by the meso\/micropore ratio. FBPC 2.5-900-2%, impregnated at a K2CO3: biochar ratio of 2.5 and a Fe3+: biochar mass ratio of 2%, and activated at 900 \u00b0C for 2 h in N2 atmosphere, has a very high specific surface area of 1996 m2 g\u22121 with a 58.1% mesoporous ratio. Moreover, it exhibits an excellent adsorption capacity of 256 mg g\u22121 and rapid adsorption kinetics for copper ions. The experimental results show that it is feasible to control the hierarchical pore structure of bamboo biochar-derived carbons as a high-performance adsorbent to remove copper ions from water.<\/jats:p>","DOI":"10.3390\/molecules26196014","type":"journal-article","created":{"date-parts":[[2021,10,8]],"date-time":"2021-10-08T21:23:55Z","timestamp":1633728235000},"page":"6014","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Preparation of Bamboo-Based Hierarchical Porous Carbon Modulated by FeCl3 towards Efficient Copper Adsorption"],"prefix":"10.3390","volume":"26","author":[{"given":"Yixin","family":"Zhang","sequence":"first","affiliation":[{"name":"National Engineering Research Center of Coal Preparation and Purification, China University of Mining and Technology, No.1 Daxue Road, Xuzhou 221116, China"},{"name":"Shandong Xuanyuan Scientific Engineering and Industrial Technology Research Institute Co., Ltd., Longgu, Juye, Heze 274918, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guofeng","family":"Qiu","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering and Technology, China University of Mining and Technology, No.1 Daxue Road, Xuzhou 221116, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rumeng","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering and Technology, China University of Mining and Technology, No.1 Daxue Road, Xuzhou 221116, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3589-1160","authenticated-orcid":false,"given":"Yang","family":"Guo","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering and Technology, China University of Mining and Technology, No.1 Daxue Road, Xuzhou 221116, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8712-3235","authenticated-orcid":false,"given":"Fanhui","family":"Guo","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering and Technology, China University of Mining and Technology, No.1 Daxue Road, Xuzhou 221116, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianjun","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering and Technology, China University of Mining and Technology, No.1 Daxue Road, Xuzhou 221116, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,10,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"235","DOI":"10.1016\/j.ecoenv.2016.07.011","article-title":"Effect of copper contaminated food on the life cycle and secondary production of Daphnia laevis","volume":"133","author":"Rocha","year":"2016","journal-title":"Ecotoxicol.
