The detection of pharmaceutical contaminants, such as Ceftriaxone (CTRX), in water sources is a critical environmental and public health concern. Conventional methods often suffer from limited sensitivity stability, making the accurate quantification low CTRX concentrations challenging. To overcome these limitations, novel amperometric sensor was developed using carbon paste electrode (CPE) modified with gold bismuth nanoparticles (Au‐BiNPs). synergistic electrocatalytic properties...
Abstract The antibiotic Ciprofloxacin (CIPRO) was investigated as a new inhibitor for copper corrosion in Synthetic Acid Rain Solution (SAR) utilizing Mass Loss (ML) chemical method, Potentiodynamic Polarization (PDP), and Electrochemical Impedance Spectroscopy (EIS) electrochemical techniques. In the presence of 600 ppm CIPRO, protection percentage reached 90.1% according to EIS technique. Thermodynamic adsorption activation characteristics were evaluated described. CIPRO on Cu surface SAR...
Abstract This paper evaluated the possibility of using quinoline derivative (an expired Moxifloxacin) as an inhibitor for copper corrosion in synthetic acid rain (SAR) solution. Weight reduction (WR) experiments, potentiodynamic polarization (PDP) and AC impedance spectra (EIS) were employed to investigate inhibition (ƞ%) rates. increases by increasing concentration MOXI all test methods. The PDP curves indicated that this medication exhibited mixed-type inhibitory activity. According EIS...
This study focused on the recycling of expired Levofloxacin hemihydrate (LFH) for preventing copper (Cu) corrosion caused by synthetic acid rain (SAR) solution employing electrochemical techniques potentiodynamic polarization (Tafel Polarization) and impedance spectroscopy (EIS); chemical method (weight loss (WL)). Results showed that LFH is an efficient inhibitor corrosion, inhibition efficiency percent (η%) reached 88.4 % at optimum concentration (600 ppm) according to EIS measurements....
