Electrostatic interactions initiate the adsorption of cationic dyes onto the geopolymer surface, while chemisorption reinforces and stabilizes the process, with both mechanisms working synergistically to enhance adsorption efficiency.

This study utilises CW laser ablation to generate titanium dioxide nanoparticles in DI water and different concentrations of polysorbate 80 at temperatures of 5 °C, 28 °C, 60 °C, and 80 °C, investigating how these factors collectively influence nanoparticle properties. Results confirmed the generation of titanium dioxide nanoparticles, showing both spherical and non-spherical particle shapes as a function of polysorbate 80 concentration. The crystallinity of the nanoparticles is observed across all temperature and concentration ranges. As the concentration increases from S1 to S5 at 28 °C, a 3.38-fold increase in size is observed, rising from 13 nm to 44 nm. The nanoparticle generation rate shows fluctuations but generally increases with temperature, reaching an average of 237.4 mg/hr at 80 °C across all concentrations.
