In this study, for the first time, a selenium-doped mesoporous biochar was prepared and efficiently employed sodium diclofenac reactive orange 16 dye adsorption. The characterization results indicated that selenium doping had remarkable impact on Biochar-Se morphological physicochemical structures. efficacy of developed samples (RO-16) (DCF) removals fully investigated. For both molecules (DCF RO-16), Liu's equilibrium model offered best fitness with maximum adsorption capacity values 355 mg g−1 DCF 538 RO-16 Biochar-Se. Multiple mechanisms including pore filling, π-π interaction, hydrogen bonding between DCF/RO-16 were involved in process. Se-nanoparticles formed metal–oxygen bonds, which boosted molecules. current work feasible approach development Se-doped adsorbent is incredibly effective treating wastewater.

Over the last years, strategy of employing inevitable organic waste and residue streams to produce valuable greener materials for a wide range applications has been proven an efficient suitable approach. In this research, sulfur-doped porous biochar was produced through single-step pyrolysis birch tree in presence zinc chloride as chemical activator. The sulfur doping process led remarkable impact on structure. Moreover, it shown that also had important sodium diclofenac (S-DCF) removal from aqueous solutions due introduction S-functionalities surface. adsorption experiments suggested General Liu models offered best fit kinetic equilibrium studies, respectively. results showed faster S-doped while maximum capacity values at 318 K were 564 mg g

Bioinspired polydopamine-sheathed carbon nanotubes as environmentally safe, efficient, and durable adsorbents for organic pollutant capturing via hydrogen bonding

Carbon, Journal Year: 2023, Volume and Issue: 214, P. 118354 - 118354

Published: Aug. 7, 2023

While the potential nanotoxicity of carbon nanomaterials likely renders them unsafe for environmental purification applications, it is still a daunting challenge to clarify specific driving force water pollutant capturing. We here employ well-documented, mussel-inspired, environmentally safe, and biocompatible polydopamine (PDA) modify surface nanotubes (CNTs) which are typical with toxicity. The PDA modification extents finely tuned by adjusting dopamine-to-CNT ratio, optimized achieved in terms homogenous formation sheath on CNT (corresponding 0.4 PC sample). limited causes bare CNTs be insufficiently covered PDA, excessive lowers adsorption capacity per unit mass adsorbent. bearing different kinds sites at atomic scale makes isothermal Rhodamine B (RhB) suitable described both Langmuir Freundlich models, maximum monolayer estimated 266.7 mg/g. Besides, PC-based RhB dictated chemisorption verified spontaneous, endothermic, entropy-gaining, anti-interference (against common metal cations tap water), repeatable process. Importantly, we disclose that hydrogen bonding pivotal process, thus enabling capture methyl orange (MO) charge state opposite RhB, equilibrium capacities calculated 135 159 mg/g MO respectively.
