This work reports the removal of diclofenac, amoxicillin, carbamazepine, and ciprofloxacin by utilizing three commercially available granular activated carbons (GACs) (Activated carbon, Silcarbon, Donau) loaded with laccase. Adsorption was used to successfully immobilize laccase on GACs, as revealed scanning electron microscopy energy dispersive X-ray analysis (SEM-EDX) Fourier transform infrared spectroscopy (FTIR). In types GACs tested, pH 5, 30 °C, 2 mg mL−1 content were found be optimum immobilization parameters. Laccase yields 65.2%, 63.1%, 62.9% achieved Donau respectively. The adsorption behaviors pharmaceuticals onto tested are best described a spontaneous endothermic process that follows Langmuir isotherm first-order kinetics. reusability immobilized enzyme evaluated using 2, 2′-azino-bis 3-ethylbenzothiazole-6-sulphonic acid (ABTS) substrate within six cycles for all adsorbents. 120 mins, nearly complete pharmaceutical compounds (50 L−1) obtained in case carbon type more than 90% other adsorbent when synergistic enzymatic degradation applied. With alone, 74% < 56% finding this study suggests biochar produced from coconut shell (same one study) can effectively removal. physical system has potential applied large-scale.

An Optimal Method of Assessing the Quality of Water Using Integrated AI and Blockchain Methodology

IGI Global eBooks, Journal Year: 2025, Volume and Issue: unknown, P. 261 - 284

Published: Feb. 18, 2025

Water quality deterioration has become increasingly severe recently due to various factors. Pollution, climate change, and population growth all contribute this issue. Contaminants such as microorganisms, heavy metals, excessive nitrogen phosphorous disrupt water pH levels, posing significant health risks. Despite advancements in IoT for maintaining balance through chlorine fluoride addition after disinfection, security threats like distributed denial of service attacks, data manipulation, session hijacking affect treatment plant operations. This compromises safety, leading problems reduced life expectancy. To address these challenges, we propose integrating AI blockchain technology into management. Our method utilizes a standard dataset on parameters total hardness classify potable or non-potable.
