TL;DR: A review of chitosan composites for removing dyes and heavy metal ions can be found in this article, where a list of composites with their adsorption capacity and experimental conditions has been compiled.

TL;DR: In this review, an extensive list of plant wastes as adsorbents including rice husks, spent grain, sawdust, sugarcane bagasse, fruit wastes, weeds and others has been compiled and some of the treated adsorbent show good adsorption capacities.

TL;DR: In this article, the adsorption of Cu(II) ions onto chitosan and cross-linked chittosan beads has been investigated and the results showed that the results correlated well with the Langmuir isotherm equation.

TL;DR: In this paper, the use of chitosan beads, CHA 1:1, 2:1 ratio beads, and CHA alginate beads for the removal of Cu(II) ions from aqueous solution at different initial pH, agitation periods, adsorbent dosage, and initial concentrations has been investigated.

TL;DR: The kinetic experimental data correlated well with the second-order kinetic model, indicating that the chemical sorption was the rate-limiting step and results showed that chitosan and cross-linked chitOSan beads were favourable adsorbers.
