摘要
In this article, the potential of alginate stabilized silver nanoparticles beads for efficient sorption of methylene blue, malachite green, and rhodamine B from aqueous solutions was investigated. The adsorption data have been correlated with both Freundlich and Langmuir adsorption models. The kinetic studies for dyes adsorption showed rapid sorption dynamics by second-order kinetic model. The common problem of classical adsorbents towards efficient recyclability was overcome when alginate stabilized silver nanoparticles beads was used. The alginate stabilized silver nanoparticles beads were successfully recycled for 25 successive adsorption-desorption cycles indicating its high reusability.
