“…The adsorption percentages of red soil, brown soil, and black soil were 1.5%-2.7%, 1.7%-6.9%, and 7.2%-12.8% at 35 ℃, respectively. Similar behavior was observed by Srivastava et al (2006), Ramadhani et al (2020), Siyal et al (2020), Niero et al (2020), and Tam et al (2020. This was possibly related to physical adsorption associated with diffusion phenomenon and ionic interactions (Khan et al 2020).…”

Desethyl-atrazine (DEA) is a metabolite of atrazine that exerts a considerable influence on the environment. In this study, tall fescue biochar was prepared by pyrolysis at 500 °C, and batch experiments were conducted to explore its effect on the adsorption behavior of DEA in red soil, brown soil, and black soil. The addition of biochar increased the equilibrium amount of DEA adsorption for the three soil types. A pseudo-second-order kinetic model most closely fit the DEA adsorption kinetics of the three soils with and without biochar, with a determination coefficient (R2) of 0.962 to 0.999. The isothermal DEA adsorption process of soils with and without biochar was optimally described by the Freundlich and Langmuir isothermal adsorption models with R2 values of 0.98 and above. The DEA adsorption process in the pristine soil involved an exothermic reaction, which became an endothermic reaction after the addition of biochar. Partitioning was dominant throughout the entire DEA adsorption process of the three pristine soils. Conversely, in soils with biochar, surface adsorption represented a greater contribution toward DEA adsorption under conditions of low equilibrium concentration. The overall results revealed that the tall fescue biochar was an effective adsorbent for DEA polluted soil.

BACKGROUNDUtilizing biowaste derived carbon materials to remediate antibiotic‐rich wastewater has considerable ecological significance in the broader ecological cycle. In this study, coconut shell activated carbon was modified using KOH hydrothermal method, and the influence of modified coconut shell activated carbon on the adsorption of amoxicillin at different particle sizes and treatment temperatures was investigated. In addition, the adsorption kinetics of amoxicillin on different modified coconut shell activated carbon was also studied.RESULTSThe study found that unmodified coconut shell activated carbon itself had a certain adsorption capacity for amoxicillin, with a maximum adsorption capacity of 22.43 mg/g. After hydrothermal‐alkali modification, the adsorption capacity of coconut shell activated carbon for amoxicillin was greatly improved, with an adsorption capacity increase of 221%. In addition, the adsorption kinetic fitting results showed that the adsorption process of amoxicillin on coconut shell activated carbon was more consistent with the pseudo‐second‐order kinetic model.CONCLUSIONThe optimal modification condition for coconut shell activated carbon is to treat coconut shell activated carbon with a particle size of 80‐120 mesh at 160°C. The findings of this study could offer a green and environmentally sustainable approach for amoxicillin‐contaminated wastewater treatment, and could also provide a certain theoretical basis for the application of biowaste resources in organic wastewater treatment.This article is protected by copyright.

“…This is primarily attributable to the challenges associated with screening bacteria that degrade antibiotics as well as the creation of ideal conditions for microorganisms to live in an aqueous environment. 5 More research has been undertaken on the removal of antibiotics by adsorption; 6,7 however, the diversity of antibiotics in the aqueous environment and the fact that a single adsorbent can only bind specific antibiotics have resulted in various limitations of the adsorption approach.

BACKGROUND: Elements of transition metals have a distinct non-nuclear electronic structure, and modifying electrodes with transition metals can increase electrocatalytic activity. Due to its low cost and high electrical conductivity, graphite felt (GF) is frequently used as the carbon base material for modified electrodes. GF was treated with KOH and subsequently loaded with the bimetal Fe and Co to create a cathode (Fe@Co/GF) with enhanced catalytic activity in this study.RESULTS: Under optimal experimental conditions (initial levofloxacin (LEV) concentration of 30 mg L −1 , electric voltage of 8 V, GF thickness of 3 mm, an aeration rate of 3 × 4.5 L min −1 , Na 2 SO 4 concentration of 0.05 mol L −1 , initial Fe 2+ concentration of 0.1 mmol L −1 , initial pH of 3, KOH activation temperature of 900 °C and Fe@Co ratio of 1:3), the LEV elimination rate was 90.38% and the mineralization rate was 88.53% within 160 min. Compared to the GF cathode, both the total LEV degradation rate and the total mineralization rate increased by approximately 20%. When Fe@Co/GF was used as the cathode in an electro-Fenton (EF) system without an applied iron source, the Fenton reaction could still occur. In addition, Fe@Co/GF also promoted the degradation of ciprofloxacin in the EF system. CONCLUSION: According to morphological and other statistical data, the modified cathode has a larger specific surface area, larger pores and a greater number of active sites. Electrochemical performance measurements indicate that the modified cathode is more responsive to current. Fe@Co/GF cathode was simple to prepare and contributed significantly to the LEV removal process when used as the cathode in an EF system, thereby decreasing the LEV degradation time.
