“…Ozonation for 4–6 min allows up to100% of TC to degrade. In turn, tetracycline removal by fenton can be about 24 mg/L [ 6 ]. Unfortunately, all these methods have many disadvantages, and they can generate free radicals and cause secondary pollution of the environment [ 6 ].…”

Chemical modification of biochars can improve their adsorption capacity relative to antibiotics, posing a serious threat to the environment. Therefore, this research is aimed at the treatment of sunflower husk biochar (BC) by vitamin C, hydrogen peroxide or silver nanoparticles and the impact of this procedure on the biochar porosity, surface chemistry, and ability to remove tetracycline (TC). During the study, BC was produced by pyrolysis of sunflower husks at 650 °C. All solids were characterized using potentiometric titration, nitrogen adsorption/desorption, Fourier transform infrared spectroscopy, etc. The experimental adsorption data was described by kinetics equations: pseudo-first order, pseudo-second order, and particle internal diffusion (IPD) models as well as by isotherms of Langmuir, Langmuir-Freundlich, and Redlich-Peterson. The obtained results indicated that the biochar upgraded by vitamin C (BCV) had the highest ability to attract antibiotic molecules and, as a result, the TC adsorption on its surface was the largest. Furthermore, the TC desorption from this material was minimal. The measured TC adsorbed amounts for the modified BCs were as follows: 47.75% (7.47 mg/g) for BCV, 37.35% (8.41 mg/g)-for biochar treated by hydrogen peroxide (BCH), and 42.04% (9.55 mg/g) for biochar modified by silver nanoparticles (BCA). The lowest adsorption level was noted for non-modified biochar, i.e., 34.17% (6.83 mg/g). Based on the presented results it can be stated that the upgraded biochars had a good potential to improve the tetracycline removal from aqueous media, e.g., groundwater.

“…Due to the wide usage and poor absorption of tetracycline, it is excreted through feces and urine and has been found in surface water, ground water, and wastewater in many places around the world [2,7]. Occurrence of antibiotics in the environment is a probable cause of increasing presence of antibiotic resistant genes and bacteria, therefore efficient removal of tetracycline from wastewater is very important [8].…”

“…Tetracycline cannot be efficiently removed by biological treatments and techniques such as membrane filtration and adsorption do not break down the tetracycline but only transfers it from one phase to another [5]. Techniques such as advanced oxidation, namely photocatalysis, ozonation, ultrasound, sonoelectrochemistry, and various combinations of advanced technologies such as ultrasound with photocatalysis have been reported as alternative water treatment approaches to the elimination of tetracycline and other recalcitrant organic compounds in wastewater [1,[7][8][9][10].…”

The mineralization of tetracycline by electrochemical advanced oxidation processes (EAOPs) as well as the study of the toxicity of its intermediates and degradation products are presented. Electro-Fenton (EF), anodic oxidation (AO), and electro-Fenton coupled with anodic oxidation (EF/AO) were used to degrade tetracycline on carbon felt (cathode) and a sub-stoichiometric titanium oxide (Ti4O7) layer deposited on Ti (anode). As compared to EF and AO, the coupled EF/AO system resulted in the highest pollutant removal efficiencies: total organic carbon removal was 69 ± 1% and 68 ± 1%, at 20 ppm and 50 ppm of initial concentration of tetracycline, respectively. The effect of electrolysis current on removal efficiency, mineralization current efficiency, energy consumption, and solution toxicity of tetracycline mineralization were investigated for 20 ppm and 50 ppm tetracycline. The EF/AO process using a Ti4O7 anode and CF cathode provides low energy and high removal efficiency of tetracycline caused by the production of hydroxyl radicals both at the surface of the non-active Ti4O7 electrode and in solution by the electro-Fenton process at the cathodic carbon felt. Complete removal of tetracycline was observed from HPLC data after 30 min at optimized conditions of 120 mA and 210 mA for 20 ppm and 50 ppm tetracycline concentrations. Degradation products were elucidated, and the toxicity of the products were measured with luminescence using Microtox® bacteria toxicity test.

“…Thus, new techniques to effectively remove tetracycline are needed. Various methods have been reported in the literature that demonstrate the removal of tetracyclines, such as adsorption, [11,12] ion exchange, [13] membrane separation, [14] and advanced oxidation process (AOPs) [15] . Among these methods, AOPs are considered a promising strategy due to their versatility, ability to degrade tetracycline efficiently, and ease of deployment in wastewater treatment plants.…”

Electrocatalytic Degradation of Tetracycline by Cu‐PANI‐SBA‐15 on Nickel Foam via Peroxymonosulfate‐Based Advanced Oxidation Process

et al. 2021

Tetracyclines are the second‐largest class of antibiotics produced and used in the world. The large‐scale use of these broad‐spectrum antibiotics and their limited metabolization by humans and animals have resulted in high levels of tetracycline discharge to the environment. In this report, we demonstrate the electrochemical peroxymonosulfate (PMS) activation using Cu(II)‐polyaniline hosted in mesoporous silica (CPS) that is deposited on nickel foam (CPS‐NF) for the degradation of tetracycline in solutions. We also propose the mechanism of the electrocatalytic processes towards the activation of PMS through various electrochemical characterization and degradation experiments. By combining PMS and a CPS‐NF cathode, nearly 90 % of tetracycline is degraded within about 5 min. The results reveal that the addition of PMS promotes the degradation of tetracycline, and the CPS‐NF cathode plays a pivotal role in activating PMS. The Cu+ and Cu2+ species induced from CPS‐NF favor the continuous activation of PMS and the production of reactive oxygen species at the surface of the CPS‐NF cathode to degrade tetracycline. This is the first time where an electrocatalyst typically used for energy applications is successfully applied to activate PMS for the degradation of an emerging pollutant in wastewater for environmental remediation.
