The adsorption ability of biochar
WebMay 1, 2024 · After UV modification, the number of oxygen-containing functional groups and the ability of adsorption greatly increased. Comparing those materials, it was found that although the adsorptive capacity of the raw materials was different, after modification, the adsorption of each UV-modified biochar was almost the same. WebApr 14, 2024 · For instance, the phosphate adsorption capacity of biochar was increased by 88.5% after modification with magnesium (Yao et al. 2013). The MgCl 2 modification of biochar introduced small masses of nanoparticles on the surface of biochar, thereby enhancing its ability to adsorb phosphate (Haddad et al. 2024).

WebIn this study, the biochar derived from waste peanut shell was modified by KMnO 4 and KOH (MBC). And a series of experiment were carried out to evaluate the sorption ability and explore adsorption mechanism of modified biochar to Ni(II). The results showed the adsorption ability of MBC to Ni(II) reached 87.15 mg g-1. WebHowever, some studies oppositely showed a limited or no ability of biochar to adsorb NO 3 2-N. For instance, Hollister et al. [13] observed no adsorption of NO 3 2 to biochar derived from corn (Zea mays L.) or oak (Quercus spp.). Yao et al. [14] found nine of thirteen biochars tested had little NO 3 2 adsorption ability and some even released NO 3
