“…As can be understood, the reduce in current at rst times is reasonably great for modi ed electrode. However, the current reaches a moderately stable quantity when the time is above 60 s demonstrating that Ni(OH) 2 -Beta/CPE displays An acceptable stability for HCHO oxidation [42]. Also, nanozeolite beta was stayed stable in the building of modi ed electrode at 0.1 M NaOH [78].…”

“…These consequences speci ed that revision of CPE with nanozeolite beta causes to improve the effective surface area of the Beta/CPE. Diffusion of Ni 2+ ions in nanozeolite beta is greatly more rapidly because of Ni 2+ coordination to the nanozeolite framework, the larger cages and channels and fast movement of Ni 2+ ions from the cages [26,42]. Also, the broad cathodic peak in some plots in Fig.…”

“…The band positioned at 1080 cm − 1 is ascribed to the external linkage asymmetrical stretching mode of Si-O-Si and can overlay with the Al-O-Si stretching mode [37,40]. The band located at about 1630 cm − 1 are ascribed to the bending vibration of H 2 O adsorbed on OH − groups [41,42].…”

In this paper, aluminosilicate nanozeolite beta has been prepared and completely described using X-ray diffraction (XRD), nitrogen sorption isotherm, Fourier transform infrared (FT-IR), transmission electron micrograph (TEM) and eld emission scanning electronic microscopy (FESEM) techniques. TEM image of synthesized nanozeolite demonstrates semispherical particles with a uniform morphology and dimensions under 50 nm. The BET surface area, total pore volume and pore diameter of it were attained to be 321 m 2 g − 1 , 0.053 cm 3 g − 1 and 1.22 nm, respectively. The modi ed carbon paste electrode by aluminosilicate nanozeolite beta and nickel hydroxide (Ni(OH) 2 -Beta/CPE) was applied for formaldehyde (HCHO) electro-catalytic oxidation in the alkaline media. The obtained results specify that Ni(OH) 2 -Beta/CPE demonstrates worthy electro-catalytic activity for oxidation of HCHO due to mesoporous construction and the great surface area of nanozeolite beta. The electron-transfer coe cient, catalytic rate constant and diffusion coe cient are found to be 0.69, 2.08×10 6 cm 3 mol − 1 s − 1 and 4.4×10 − 7 cm 2 s − 1 , respectively. The Ni(OH) 2 -Beta/CPE exhibited good reproducibility and stability and it has low price, low background current, simplicity of surface renewal. This modi ed electrode has better poisoning tolerance capability than bare CPE for HCHO electro-catalytic oxidation and is a higher device for the long term accomplishment.

“…Before the deposition of the TiO2 coating, the surface of the titanium plate had been etched with oxygen plasma for 3 min at 100 W of RF power. Subsequently, we employed plasma-enhanced chemical vapor to deposit TiO2 onto the titanium plate at a power level of 200 W, flow rate of oxygen = 40 mL/min, flow rate of Existing methods for degrading antibiotics mainly include the ozone oxidation method [6], Fenton oxidation method [7,8], catalytic wet oxidation method [9,10], photocatalytic oxidation method [11,12], and electrocatalytic oxidation [13,14] methods. Among them, the electrocatalytic oxidation method has received wide attention from scholars because of its excellent selectivity, high degradation efficiency, few byproducts, and operability under normal temperature and pressure [15][16][17][18].…”

Presently, in the context of the novel coronavirus pneumonia epidemic, several antibiotics are overused in hospitals, causing heavy pressure on the hospital’s wastewater treatment process. Therefore, developing stable, safe, and efficient hospital wastewater treatment equipment is crucial. Herein, a bench-scale electrooxidation equipment for hospital wastewater was used to evaluate the removal effect of the main antibiotic levofloxacin (LVX) in hospital wastewater using response surface methodology (RSM). During the degradation process, the influence of the following five factors on total organic carbon (TOC) removal was discussed and the best reaction condition was obtained: current density, initial pH, flow rate, chloride ion concentration, and reaction time of 39.6 A/m2, 6.5, 50 mL/min, 4‰, and 120 min, respectively. The TOC removal could reach 41% after a reaction time of 120 min, which was consistent with the result predicted by the response surface (40.48%). Moreover, the morphology and properties of the electrode were analyzed. The degradation pathway of LVX was analyzed using high-performance liquid chromatography–mass spectrometry (LC–MS). Subsequently, the bench-scale electrooxidation equipment was changed into onboard-scale electrooxidation equipment, and the onboard-scale equipment was promoted to several hospitals in Dalian.
