Optimization and Modeling of Tetracycline Removal from Wastewater by Three-Dimensional Electrochemical System: Application of Response Surface Methodology and Least Squares Support Vector Machine

Loofah activated carbon with hierarchical structures for high-efficiency adsorption of multi-level antibiotic pollutants

“…𝑡 𝑞 𝑒 (6) qe stands for the equilibrium adsorption capacity (mg g -1 ), while qt is the adsorption capacity (mg g -1 ) at time t. K1 is the pseudo-first-order adsorption rate constant, as well as K2 rate constant of formula (6). The fitting figures of three various antibiotics are given in Table 3.…”

“…[4,5] After excretion of antibiotics from body, they will remine almost unchanged in water bodies. [6] Therefore, the removal of antibiotics residues from polluted water is of significant importance for both human health and the aquatic environment. Moreover, low concentrations of antibiotics were reported to cause more serious hazards to human health and ecological environment than high concentrations of them.…”

Ultrasound-assisted sorption of Pb(ii) on multi-walled carbon nanotube in presence of natural organic matter: an insight into main and interaction effects using modelling approaches of RSM and BRT

“…39 However, the success of a BRT model relies on optimal sets of these regularization parameters. Hence, BRT models with various nt (1 to 100), tc (1,4,16) and lr (0.1, 0.25, 0.50, and 1.00) values were considered in the training to select the best BRT model with maximum R 2 and minimum error.…”

“…Multivariate statistical strategies have been preferred to the OVAT approach to identify the optimal combination of parameters and interactions between variables, improve cost-and time-effectiveness, develop a mathematical model, forecast the response, assess the model adequacy, and determine the optimal conditions for a given response. 16,17 Response surface methodology (RSM) is known as an efficient procedure applicable not only to experimental design but also to development of a mathematical model (linear, square polynomial functions, etc.) for each response based on the obtained results.…”

Photocatalytic Degradation of Tetracycline by ZnO/γ-Fe2O3 Paramagnetic Nanocomposite Material

“…Therefore, the design and development of new technological approaches able to remove tetracyclines from wastewater before their discharge into aquatic environments are required. Among the various wastewater treatments, which include biodegradation, adsorption, electrochemical degradation and ozonation [ 10 , 11 , 12 , 13 ], new methods based on advanced oxidation processes (AOPs) have been recently developed [ 9 ]. AOPs involve the use of photocatalytic systems, such as zinc oxide (ZnO) or titanium dioxide (TiO 2 ) nanoparticles, that produce hydroxyl radicals (∙OH) in situ under electromagnetic radiation [ 14 , 15 ].…”
