Abstract

The carbon materials are widely used as activators for peroxymonosulfate (PMS) to degrade organic pollutants in water. In this study, bamboo scraps, a typical biochar resource in Jiangxi Province, China, was used as raw material to prepare biochar by high temperature (700, 800, 900 °C) pyrolysis and KOH activation, and its morphology, structure and physicochemical characteristics were characterized and analyzed. The results showed that BB-KOH-900 biochar prepared under the optimized conditions of 900 °C could effectively activate PMS and achieve 91.1 % Tetracycline (TC) removal rate within 60 min. Electron paramagnetic resonance (EPR) and quenching experiments showed that 1O2 was the main active factor, and the non-radical pathway dominated by 1O2 was the main pathway for Tetracycline degradation. Characterization analysis confirmed that carbonyl groups CO, graphite nitrogen (N) and structural defects (ID/IG) were the main reaction sites for activating PMS to degrade Tetracycline. Moreover, the degradation pathways of Tetracycline were proposed and the tocixities of intermediates were evaluated. Our research not only provides a feasible method for the recycling of bamboo scraps, but also makes its Fenton- like application possible with an economical, green and recyclable carbon catalyst.

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
