In this study, the effects of biomass type, pre-carbonization process, and activation method on the properties of ACs were investigated. Chemical (KOH and H3PO4) and physical (CO2) activations were performed on slow pyrolyzed and hydrothermally carbonized (HTC) biochars produced from two feedstocks, willow and Scots pine bark (SPB). In addition, the adsorption capacities of the ACs were tested with two dyes and zinc metal. Distinct differences were found between the biochars and ACs regarding pore size distributions, surface area (238 \uffe2\uff80\uff93 3505 m2 g-1), and surface chemistry. KOH activation produced highly microporous ACs from all biochars, whereas with H3PO4 and CO2 there was also increase in the meso- and macroporosity with the HTC biochars. Adsorption capacity for dyes was dependent on the surface area, while for zinc it depended on AC\uffe2\uff80\uff99s pH. The results provide interesting insights into tailoring ACs for specific applications.</p>", "keywords": ["bark", "willow", "biohiili", "330", "Willow", "Activated carbon", "Activated carbon;", "pine bark", "pajut", "Pinus sylvestris", "tomography", "bio-based activated carbon", "620", "Biochar", "tomografia", "Pine bark", "SDG 13 - Climate Action", "Bio-based activated carbon", "activated carbon", "biochar", "ta219", "SDG 7 - Affordable and Clean Energy", "X-ray tomography"]}, "links": [{"href": "https://bioresources.cnr.ncsu.edu/wp-content/uploads/2018/06/BioRes_13_3_5976_Siipola_Effects_Biomass_Type_Carbonizat_Process_Activat_Method_Activ_C_13985.pdf"}, {"href": "https://doi.org/10.15376/biores.13.3.5976-6002"}, {"rel": "related", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/BioResources", "name": "related record", "description": "related record", "type": "application/json"}, {"rel": "self", "type": "application/geo+json", "title": "10.15376/biores.13.3.5976-6002", "name": "item", "description": "10.15376/biores.13.3.5976-6002", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/10.15376/biores.13.3.5976-6002"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2018-06-15T00:00:00Z"}}], "links": [{"rel": "self", "type": "application/geo+json", "title": "This document as GeoJSON", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=bio-based+activated+carbon&f=json", "hreflang": "en-US"}, {"rel": "alternate", "type": "text/html", "title": "This document as HTML", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=bio-based+activated+carbon&f=html", "hreflang": "en-US"}, {"rel": "collection", "type": "application/json", "title": "Collection URL", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main", "hreflang": "en-US"}, {"type": "application/geo+json", "rel": "first", "title": "items (first)", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=bio-based+activated+carbon&", "hreflang": "en-US"}, {"rel": "last", "type": "application/geo+json", "title": "items (last)", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=bio-based+activated+carbon&offset=1", "hreflang": "en-US"}], "numberMatched": 1, "numberReturned": 1, "distributedFeatures": [], "timeStamp": "2026-07-28T20:12:11.830832Z"}
