Bio Materials and Nanotechnology: Green Tea (Waste)– Aluminium Nanoparticles (Gt-Al Nps) For Methylene Blue Adsorption
Abstract: This study examines the adsorption of Methylene Blue (MB) dye from aqueous solutions using Aluminium Nanoparticles synthesized with green tea powder as a biological reducing agent. Methylene Blue, an aromatic phenothiazine dye, is widely applied in medical diagnostics and various industrial processes, but its uncontrolled release into water bodies leads to environmental pollution due to its intense colour, stability, and potential toxicity. Therefore, identifying an efficient and eco-friendly adsorbent for …

Adsorptive Removal of Rhodamine-B Using Eco- Synthesized Green Tea–Aluminium Nanoparticles
Abstract: This study examines the use of Green Tea–Aluminium Nanoparticles (GT-Al NPs), a unique and eco-friendly adsorbent, to remove the dangerous Rhodamine-B dye from water. For characterisation, SEM, FTIR, TGA, and EDX were employed. We evaluated the effects of pH, temperature, dosage, contact time, and initial dye concentration on adsorption efficiency. First- and second-order pseudo models were used to characterize adsorption kinetics, and the Langmuir model explained equilibrium, as well as …
