Abstract

In this study, a method for preparing activated carbon (AC) from wheat dust (WD) was developed to achieve efficient removal of tetracycline hydrochloride (TCH). The AC, prepared through response surface methodology with a carbonization temperature of 590 °C, a NaOH to WD ratio of 4:1, and an activation temperature of 800 °C, exhibited a high specific surface area of 2821.58 m²/g. It demonstrated a remarkable TCH removal capacity of 1414.65 mg/g in aqueous solution. The AC retained an adsorption capacity of 1035.36 mg/g after five cycles and maintained over 80% of its adsorption capacity in different water bodies. The adsorption of TCH by AC, primarily controlled by surface sites through chemical and physical interactions, involved mechanisms such as pore-filling, electrostatic interactions, hydrogen bonding, π-cation interactions, and π-π interactions. This study highlights the potential of WD in preparing effective adsorbents, providing valuable insights for the comprehensive utilization of similar byproducts.

期刊介绍： The word ‘particuology’ was coined to parallel the discipline for the science and technology of particles. Particuology is an interdisciplinary journal that publishes frontier research articles and critical reviews on the discovery, formulation and engineering of particulate materials, processes and systems. It especially welcomes contributions utilising advanced theoretical, modelling and measurement methods to enable the discovery and creation of new particulate materials, and the manufacturing of functional particulate-based products, such as sensors. Papers are handled by Thematic Editors who oversee contributions from specific subject fields. These fields are classified into: Particle Synthesis and Modification; Particle Characterization and Measurement; Granular Systems and Bulk Solids Technology; Fluidization and Particle-Fluid Systems; Aerosols; and Applications of Particle Technology. Key topics concerning the creation and processing of particulates include: -Modelling and simulation of particle formation, collective behaviour of particles and systems for particle production over a broad spectrum of length scales -Mining of experimental data for particle synthesis and surface properties to facilitate the creation of new materials and processes -Particle design and preparation including controlled response and sensing functionalities in formation, delivery systems and biological systems, etc. -Experimental and computational methods for visualization and analysis of particulate system. These topics are broadly relevant to the production of materials, pharmaceuticals and food, and to the conversion of energy resources to fuels and protection of the environment.
