TLDR
D dye/chitosan interaction showed favorable enthalpic and entropic processes, reflecting thermodynamic stability of the formed complex, while dye/ chitin interaction showed an exothermicEnthalpic value and a highly nonfavorable entropics effect, resulting in a nonspontaneous thermodynamic system.About:

Journal ArticleDOI
A review of chitin and chitosan applications
TL;DR: Chitin is the most abundant natural amino polysaccharide and is estimated to be produced annually almost as much as cellulose, and recent progress in chitin chemistry is quite noteworthy as mentioned in this paper.
Journal ArticleDOI
Low-cost adsorbents for heavy metals uptake from contaminated water: a review.
TL;DR: The technical feasibility of various low-cost adsorbents for heavy metal removal from contaminated water has been reviewed and it is evident from the literature survey of about 100 papers that low- cost adsorbent have demonstrated outstanding removal capabilities for certain metal ions as compared to activated carbon.

Adsorption behavior of reactive dye in aqueous solution on chemical cross-linked chitosan beads.
M.S Chiou,H.Y Li +1 more
TL;DR: The adsorption mechanism is shown to be the electrostatic interactions between the dye and chitosan beads and the dynamical data fit well with the second-order kinetic model, except for the dry beads fitting better with the first-order model.

Equilibrium and kinetic modeling of adsorption of reactive dye on cross-linked chitosan beads
Ming Shen Chiou,Hsing Ya Li +1 more
TL;DR: The experimental data fitted well to the second-order kinetic model, which indicates that the chemical sorption is the rate-limiting step, instead of mass transfer, in the reactive dye adsorption system.
