Bio-hydrogen Production Using Modified Zeolite Decorated with Green Iron Oxide Nanoparticles During the Fermentation Process from Food Industry Wastewater
Published 2024-11-01“…The optimal conditions were found to be a nanoparticle concentration of 300 mg/L, a pH of 5.5, and a temperature of 36 degrees Celsius, leading to a hydrogen production efficiency of 250.8 mL. These results show that nanoparticles at specific concentrations enhance bacterial activity by affecting intracellular enzymes, thereby improving efficiency. …”
