Heat-resistant boron Carbonitride with nitrogen-vacancies and oxygen-doping for efficient tetracycline removal: Adsorption characteristics, mechanism and regeneration
The increasing environmental risks associated with tetracycline (TC) have been of widespread interest in the development of adsorbents for the efficient treatment of TC. This work synthesized a high-performance boron carbonitride (BCNvO) with nitrogen-vacancies (Nv) and oxygen-doping (Od) via a hydrogen peroxide mediated strategy. The adsorption capacity of BCNvO-1 for TC (202.85 mg/g) is 1.79 times higher than that of BCN (113.08 mg/g). The adsorption process is well described by the pseudo-second-order kinetic and controlled by surface and intra-pore diffusion. Langmuir can well characterize isothermal adsorption with the fitted maximum adsorption up to 440.53 mg/g. Thermodynamics indicates a spontaneous and endothermic progress in BCNvO-1 adsorption. The abundant pore structures promote pore filling of TC by BCNvO-1. Nv and Od enhance BCNvO-1 proton capture, and the captured protons strengthen hydrogen bonding and electrostatic interactions during adsorption. The functional groups, aromatic regions, and BN rings on BCNvO-1 are involved in hydrogen bonding and π-π stacking to TC. BCNvO-1 has high adsorption performance, great environmental appropriateness and thermal regeneration performance, suggesting good prospects for its potential application in environmental wastewater treatment.
期刊介绍：
The Journal of Water Process Engineering aims to publish refereed, high-quality research papers with significant novelty and impact in all areas of the engineering of water and wastewater processing . Papers on advanced and novel treatment processes and technologies are particularly welcome. The Journal considers papers in areas such as nanotechnology and biotechnology applications in water, novel oxidation and separation processes, membrane processes (except those for desalination) , catalytic processes for the removal of water contaminants, sustainable processes, water reuse and recycling, water use and wastewater minimization, integrated/hybrid technology, process modeling of water treatment and novel treatment processes. Submissions on the subject of adsorbents, including standard measurements of adsorption kinetics and equilibrium will only be considered if there is a genuine case for novelty and contribution, for example highly novel, sustainable adsorbents and their use: papers on activated carbon-type materials derived from natural matter, or surfactant-modified clays and related minerals, would not fulfil this criterion. The Journal particularly welcomes contributions involving environmentally, economically and socially sustainable technology for water treatment, including those which are energy-efficient, with minimal or no chemical consumption, and capable of water recycling and reuse that minimizes the direct disposal of wastewater to the aquatic environment. Papers that describe novel ideas for solving issues related to water quality and availability are also welcome, as are those that show the transfer of techniques from other disciplines. The Journal will consider papers dealing with processes for various water matrices including drinking water (except desalination), domestic, urban and industrial wastewaters, in addition to their residues. It is expected that the journal will be of particular relevance to chemical and process engineers working in the field. The Journal welcomes Full Text papers, Short Communications, State-of-the-Art Reviews and Letters to Editors and Case Studies
