Kinetic studies of dye adsorption by Cds quantum dots nanocomposites hydrogels

In this work cadmium sulfide quantum dots was synthesized by using in situ synthesizing method in crosslinked κ-carrageenan hydrogel. The effects of various parameters such as adsorbent dosage, pH, contact time, initial dye concentration, and temperature on the adsorption of crystal violet (CV) were studied. The photocatalytic effect and dye adsorption isotherms were investigated by the quantum dots nanocomposites hydrogels. Kinetic studies were also performed by using different kinetic models to investigate the dye adsorption.
