“…All ABs seem to exhibit three peaks in the FTIR spectra, including the stretching vibration of the –OH group, 43 CO/CC, 44 and C–O. 45 The CO peak may belong to aldehydes, ketones, and carboxylic acids. The CC peak may be caused by the backbone vibration of the substituted benzene ring.…”

“…The mixture was stirred continuously. Samples were drawn at 45,60,90,120,170,200, and 240 min. The kinetics of the adsorption were modeled using the pseudo-first-order (PFO), pseudo-second-order (PSO), Elovich kinetic, and Weber-Morris models:…”
The phenol adsorbent-activated biochar (AB) has a high potential. The coupling effects of porous structure, graphite microcrystals and oxygen-containing groups of biochar are key concerns for phenol removal from water....

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
