Preparation and characterization of a clam shell powder/carrageenan composite for methylene blue adsorption

Year: 2026

Type: article

Abstract: . The adsorption process followed the pseudo-second-order kinetic model, and the equilibrium data were best described by the Langmuir isotherm model. Furthermore, CSP@Car-1 maintained adsorption activity after five adsorption-desorption cycles, although adsorption performance gradually decreased with repeated regeneration. These findings indicate that CSP@Car-1 is a promising low-cost and eco-friendly adsorbent for dye removal from wastewater, although further enhancement of its regeneration stability is necessary for practical applications.
