Chitosan is a natural amino polymer. It is eco-friendly, biocompatible, biodegradable, cost-effective, easily available and has high potential to be utilized as an adsorbent. Because of their excellent chelating power, chitosan-based adsorbents have a very high ability to tightly bind the pollutants present in contaminated water and wastewater. Different heavy metals and toxic dyes can be effectively removed. Chapter 1 deals with the chemical, physical, physicochemical and mechanical properties of chitosan and chitosan-based materials. Adsorption data on the removal of heavy metals and different dyes have been compiled. Chapter 2 covers the utilization of chitosan and its derivatives for the adsorptive removal of mercury from water and wastewater. Chapter 3 describes novel chitosan-based nanocomposites for dye removal applications. Chapter 4 discusses the effect of different chitosan modifications on its structure and specific surface area. Chapter 5 covers the applications of chitin and chitosan-based adsorbents for the removal of natural dyes from wastewater. Chapter 6 highlights the adsorptive treatment of textile effluents using chemically modified chitosan as adsorbents. Chapter 7 reviews the applications of chitosan-based adsorbents for the removal of arsenicals. Chapter 8 centers on the adsorption capacity enhancement of chitosan by chemical modification. Chapter 9 focuses on the smart use of surfactants for the modification of chitosan and some other biomaterials and their subsequent use for the removal of contaminants from aqueous solutions. Chapter 10 reviews the use of chitosan-based nanocomposites as adsorbents for the removal of dyes from wastewater. Chapter 11 describes the preparation of uniformly distributed platinum nanoparticles decorated with graphene oxide-chitosan by employing a microwave-assisted method. The nanocomposite can be used for the removal of dye from aqueous solution.

The forms of utility in the wastewater treatment of chitosan-based adsorbents acquired from natural substances have attracted numerous attentions in recent years. The use of chitosan modified adsorbents for removal of the chromium has aroused great interest. When chitosan-based modified adsorbents are considered, they have got large amount of an amino (-NH2) and hydroxyl (-OH) functional groups. Such adsorbents display that they have high activity and therefore they may be extensively utilized in wastewater treatment plants to cast off chromium. In this chapter, the utility outcomes of chitosan-based substances will be explained after applying different parameters to remove Cr (VI) from the aqueous surrounding with the information obtained the use of batch adsorption systems. Application of various chitosan-based adsorbents for Cr (VI) removal application will be demonstrated in a detailed way and they will be discussed within the textual content.

The focus of this research was to investigate and study the modified crosslinked chitosan beads as an adsorbent to adsorb the excessive residue oil from an oily wastewater. Palm oil mill effluent (POME) from the local palm oil mill was used as a sample of an oily wastewater. Raw chitosan present some limitations such as unsatisfactory mechanical properties, poor heat resistance and soluble in dilute acid aqueous solution. Crosslinking has been proposed in this study to overcome such weakness. Three types of crosslink agent, namely glutaraldehyde (GLA), ethylene glycol diglycidyl ether (EGDE) and epichlorohydrin (ECH) were used for this purpose. Series of batch adsorption experiments were carried out using different conditions and parameters. The controlled variables were adsorbent dosage, agitation rate, contact time and pH. A detailed batch study on chitosan flakes and the crosslinked chitosan beads with respect to its adsorption equilibrium, isotherm and kinetic study were also carried out. The best removal of residue oil was accomplished using chitosan flakes as adsorbent with adsorbent dosage of 15 g adsorbent per liter of POME, agitation rate of 100 rpm, contact time of 1 hr and pH of 6.0. Fourier transform infrared (FTIR) spectrophotometer and scanning electron microscope (SEM) images of chitosan flakes and crosslinked chitosan beads before and after the adsorption experiments were presented to prove that the residue oil had been adsorbed by these adsorbents. The Langmuir isotherm model provided the best fit for the equilibrium data in the concentration range investigated, with the maximum adsorption capacity being 131.58 mg of residue oil per gram of chitosan flakes, as obtained from the linear equation of the isotherm. The adsorption kinetics was tested using three models: pseudo-first-order, pseudo-second-order and intraparticle diffusion model. The experimental kinetics data were properly correlated with the pseudo-second-order kinetic model (R2=0.9996), which provided a rate constant, k2, of 0.0021 g/mg.min. The research study had attested chitosan and crosslinked chitosan beads as a potential adsorbent to adsorb residue oil from POME.
