A zeolitic sample, named MT-ZLSH, was synthesized using mining tailings (MT) as the precursor material, resulting in a structure comprising: Linde type (LTA) and sodalite-hydroxysodalite (ZLSH). This naming convention reflects material’s origin its structural characteristics. The material further modified by incorporating lithium, producing MT-ZLSH-Li+. Physicochemical characterizations were performed, evaluated for potential to remove methylene blue (MB) from synthetic wastewater through adsorption photocatalysis. Efficient observed under typical pH conditions, with maximum capacity of 23.4 mg·g−1, which fit well Langmuir isotherm model. key mechanisms governing MB identified ion exchange, electrostatic attraction, hydrogen bonding. process exothermic, kinetic data fitting both pseudo-second order intraparticle diffusion models, achieving 82% removal 40 mg·g−1 over 12 h. followed two-step process, initially involving film diffusion, diffusion. Additionally, photocatalytic degradation achieved 77% within 180 min. However, decrease reusability during second cycle photodegradation, highlighting need optimization enhance long-term performance.

Adsorptive Removal of Dyes: A Comparison of Graphene Oxide to Granular Activated Carbon and Zeolite NaY

Applied Sciences, Journal Year: 2024, Volume and Issue: 14(21), P. 9811 - 9811

Synthetic carbon-based compounds are a prevalent wastewater contaminant that can adversely impact water resources due to their potential carcinogenic and toxic effects on aquatic biota human health. This research investigates the versatility of graphene oxide (GO) as an alternative commonly used adsorbents (zeolite NaY (NaY) granular activated carbon (GAC)) for removal synthetic cationic dyes. Rhodamine B (RhB) methylene blue (MB), were selected target contaminants represent dyes with differing molecular sizes structural compositions. Batch experiments using GO, NaY, GAC assess both physicochemical interactions between adsorbent surfaces contaminants, efficiency. GO demonstrated highest efficiency contaminants—at 99% 86%, respectively—while lowest was observed NaY. Langmuir, Freundlich, Temkin, BET isotherm models describe adsorption isotherms. Overall, more robust higher compared indicating complex structured organic in treatment.
