Abstract

Silver oxide titanate nanotubes (Ag2O@TNTs) and silver oxide titanate nanofibers (Ag2O@TNFs) were synthesized by hydrothermal method with high alkalinity and used as adsorbents to remove iodine ions from aqueous solutions. The synthesized adsorbents, characterized by using X-ray Diffraction, Fourier Transform Infrared Spectroscopy, Scanning Electron Microscope, Transmission Electron Microscopy, and Brunauer–Emmett–Teller and Zeta-potential analysis. We evaluated iodine ion adsorption on Ag2O@TNTs and Ag2O@TNFs based on various factors like contact time, pH, initial concentration, adsorbent weight, and temperature through batch experiments. Our findings identified the optimal conditions for I− ion adsorption: pH 7, an initial concentration of 100 mg L−1, 0.05 g of adsorbent per 20 ml, temperature = 25 ± 1 °C, and about 30 min of contact time. The pseudo-second-order model best describes the adsorption kinetics, and the Langmuir model fits the adsorption isotherms more closely. The maximum uptake capacity of I− ions was found from the Langmuir model for I− ions was 344.83 (mg g−1) and 277.77 (mg g−1) at 298 K and removal rates of 83.4% and 78.8%, for Ag2O@TNT and Ag2O@TNF, respectively. The separation factor (RL) value for Ag2O@TNT is 0.67 and for Ag2O@TNF is 0.65, which confirms the of favorability adsorption. Thermodynamic assessments show that both adsorbents undergo favorable, spontaneous, and endothermic adsorption processes, offering an efficient mechanism for I− ion extraction from aqueous solutions. A comparative assessment revealed that titanate nanotubes outperform titanate nanofibers in terms of I− ion adsorption capacity and efficiency.
