Functionalization of Cellulose with Cysteamine: Synthesis, Characterization, and Adsorption

Abstract:

The cellulose matrix was chemically modified with cysteamine (CelCTA) and characterized by elemental analysis, and subsequently applied to the removal of copper ion in an aqueous media. The experimental adsorption isotherm obtained for the studied system was adjusted to linear models: Langmuir, Freundlich, and Temkin. Among the proposed models, the Langmuir model was the one with the best linear adjustment to data obtainedexperimentally, with an adsorption capacity of the adsorbent for 0.3292 mmol dm^-3.
