Straw-derived biochar for the removal of antibiotics from water: Adsorption and degradation mechanisms, recent advancements and challenges

Synthesis of Ag/ZnO/BiOCl Composite Material and Its Photodegradation Performance on Ciprofloxacin

“…E CB = χ − E e + 0.5E g (1) E VB = E CB + E g (2) In these equations, χ represents the absolute electronegativity of the semiconductor; E e is the free electron energy on the hydrogen scale (4.5 eV); and E g is the bandgap energy of the semiconductor.…”

“…The management of antibiotic wastewater is challenging due to its large-scale discharge, which can be quantified in millions of liters per day globally, and its notable resistance to degradation, with some antibiotics exhibiting half-lives extending over several months under environmental conditions [1][2][3][4][5]. Conventional treatment methods such as adsorption, coagulation, membrane filtration, and advanced oxidation processes have distinct limitations [6][7][8][9][10][11][12][13].…”

ZnCl2 activated mesoporous carbon from rice straw: optimization of its synthetic process and its application as a highly efficient adsorbent for amoxicillin

“…9,[11][12][13] However, poor adsorption performance was found in the case of raw biochar; therefore, a modification process is necessary for improving the adsorption efficiency of the materials. 14 Examples of modification methods to improve the antibiotic adsorption of rice straw-derived biochar include tannic acid modification, 15 modification with TiO 2 , 16 magnetization method 9 and chemical activation. 17 Chemical activation of rice straw has been used to enhance the adsorption of various adsorbates such metals and dyes; however, limited studies have been reported on antibiotics.…”

Enhanced Degradation of Levofloxacin through Visible-Light-Driven Peroxymonosulfate Activation over CuInS2/g-C3N4 Heterojunctions

“…Many treatment methods have been applied to degrade various antibiotics, such as the activated sludge method, adsorption method, and advanced oxidation technology [ 15 , 16 , 17 ]. Among various AOPs, sulfate radical-based advanced oxidation processes (SR-AOPs) have received more attention owing to their simple operation equipment, mild reaction conditions, low cost, long lifespan, and high catalytic efficiency [ 18 , 19 , 20 ].…”
