Adsorption of Methylene Blue onto Polydopamine-Functionalized Halloysite Nanotubes: Kinetics and Equilibrium Studies.

ABSTRACT: The elimination of synthetic dyes from industrial effluents represents a persistent environmental challenge. Developing sustainable and effective adsorbents is essential to preserve global water resources. In this study, we introduce an efficient and facile strategy for methylene blue removal from aqueous systems using halloysite nanotubes functionalized with polydopamine. The polydopamine coating generated a dense array of active adsorption sites, as confirmed by X-ray photoelectron spectroscopy, energy-dispersive X-ray spectroscopy, thermogravimetric analysis, and zeta potential measurements. Porosity characterization and X-ray diffraction provided complementary insight into the structure and morphology of the hybrid nanotubes. We systematically investigated the influence of contact dura
