“…Optimizing of experimental parameters of photo-induced and sonocatalytic degradation revealed a ceftriaxone removal efficiency ranging between 70% and 95% [12][13][14][15][16]. These methods were also used for ceftriaxone degradation in the presence of carbon nitride (g-C 3 N 4 ) and different composite materials such as Ag-CsPbBr 3 , ZnSe, BiWO 6 [17][18][19][20][21].…”

The electrochemical stability of ceftriaxone (CFTX), belonging to the third generation of cephalosporin antibiotics, was studied by electrochemical measurements recorded on a platinum electrode (Pt) in aqueous solutions containing sodium halides. The electrochemical behavior of ceftriaxone was investigated by cyclic voltammetry (CV) and constant current density electrolysis assisted by UV-Vis spectrophotometry. Cyclic voltammetry highlighted that the addition of CFTX in sodium halide solutions leads to significant changes in the hysteresis characteristics due to specific interactions with active species from electrolytes, as well as with the platinum electrode surface. After CV, when an exterior electric stimulus in short time (40 s) was applied, the UV-Vis spectra illustrated that CFTX is stable in the presence of F- ions, it is electro(degraded/transformed) in the presence of Cl- and Br- ions and interacts instantly with I- species. Electrolysis at constant current density confirms the results obtained from cyclic voltammetry, showing that (i) in the presence of fluoride ions CFTX gradually decomposes, but not completely, in about 60 min, without identifying a reaction product; (ii) chloride and bromide ions determine the almost complete CFTX electro(degradation/transformation) in 10 and 5 min, respectively, with completion of the electro-transformation reaction after 60 and 30 min, respectively; (iii) instantaneous interactions between CFTX and the iodide ions occurred.

“…Using RSM as the appropriate mathematical and statistical method, it is possible to provide a model that correlates the various experimental variables (such as the initial concentration of pollutant, pH, irradiation time, the amount of photocatalyst) and the response (photodegradation percentage) obtained by performing fewer tests with greater accuracy. In the RSM category, central composite design (CCD) has been widely used for the optimization of the photocatalytic degradation process because of the advantage of optimizing multifactor problems with the optimum number of experimental runs [3].…”

In this research, the cadmium sulfide -graphite carbon nitride (CdS-g-C3N4) nanocomposite was synthesized and characterized by X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM), energy-dispersive X-ray spectrometer (EDX), and transmission electron microscopy (TEM) techniques. The photocatalytic activity of asprepared nanocomposite was evaluated in the degradation of ceftriaxone sodium (CTX) antibiotic from aqueous solution under visible light irradiation. The influence of the operational variables such as the amount of photocatalyst (g/L), initial CTX concentration (mg/L), pH, and irradiation time (min) on the photodegradation process was investigated and optimized using response surface methodology (RSM) -central composite design (CCD) model. The maximum degradation percentage (92.55 %) was obtained in the optimal condition, including 0.06 g/L of CdS-g-C3N4 photocatalyst, 15 mg/L of CTX, pH= 10.5, and irradiation time = 81 min. The efficient photocatalytic performance of CdS-g-C3N4 nanocomposite is due to the appropriate alignment of energy levels between the CdS and g-C3N4, which synergistically impact the charge separation and the degradation efficiency of CTX. The kinetics of the photocatalytic degradation process was well described by Langmuir-Hinshelwood's pseudo-first-order model (kapp = 0.0336 min -1 ).

This work studies the effects of varying erbium dopant percentages on the optical, structural, morphological,elemental, and electrical properties of zirconium telluride thin films deposited via electrochemical deposition technique.The obtained films were characterized using Uv-Visible Spectrophotometer, X-ray diffractometer (XRD), scanning electron microscope (SEM), energy dispersive x-ray spectroscope (EDX), and a four-point probe system. XRD analyses showed cubic polycrystalline films with the most intense peak at (111) plane. SEM micrographs revealed spherical balls while EDX spectra confirmed the deposition of basic elements. Good optical features and decreased band gap energies from 1.80 eV to 1.76 eV were observed upon addition of erbium. The electrical conductivities of the films improved significantly upon doping. The deposited films are potential solar cells, and optical materials.
