Biopolymers (chitin, chitosan) like potential adsorbents are often challenged by weak stability, poor dispersibility, low adsorption, and difficulty of recovery. This work demonstrates the synthesis of an adsorbent in the form of CS/MWCNTs/Fe beads by combining chitosan and sodium alginate with magnetic iron oxide-doped MWCNTs. The prepared composite beads were then used for the adsorption of Cr(VI) from water samples. The physicochemical properties of CS/MWCNTs/Fe beads were characterized in detail by using FTIR, XRD, FE-SEM, EDS, and TGA. The outer to inner core structural characterization of composite beads found that the magnetic iron oxide-doped MWCNTs coated with chitosan were uniformly dispersed inside the alginate beads, making their shape as a spherical shell. During the adsorption experiments, CS/MWCNTs/Fe beads showed robust performance in Cr(VI) removal and could separate easily by using external magnet from the aqueous sample having the initial concentration, solution pH and temperature as critical factors to control their removal performance. We demonstrated that these beads can achieve a high Cr(VI) removal performance with an optimized chitosan and alginate contents. The pseudo-second-order model showed the best fit with experimental data, suggesting the rate-limiting factor of the adsorption. Langmuir isotherm with a maximum adsorption capacity of 11.74 mg/g characterized the Cr(VI) removal behavior. Moreover, the composite beads showed up to 76% of Cr(VI) removal efficiency after five cycles of adsorption. The synergistic impact in this process suggests the promising potential of CS/MWCNTs/Fe beads for the elimination of contaminants from the water bodies.

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 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 progress of society has led to an improvement of the quality of life of a significant number of people. On the other hand, anthropogenic pollution dramatically increased, with serious consequences for the environment and human health. Controlling and remedying environmental pollution is one of the main challenges of our century. Fundamental and applicative research are called to collaborate, involving scientists in the development of realistic and effective systems for the prevention and the removal of pollutants from the environment. Spreading knowledge is among the missions of researchers and this is the aim of this book, offering an updated view on innovative materials and methods for pollutant treatment. It is composed of 18 articles, among them 5 reviews and 13 original articles, dedicated to new adsorbent materials (inorganic, organic, and hybrid materials) for the capture of pollutant species and for their catalytic conversion into non-toxic substances, and to bioremediation approaches to treat contaminated media. Water, air, and soil pollution was investigated, both at the lab and large scale, with special relevance for wastewater treatments for the removal of heavy metals and organic pollutants. We are grateful to "Molecules" for the opportunity to edit the Special Issue on "Innovative Materials and Methods for the Removal of Pollutants from the Environment". We created, for this book, an original cover image, dedicated to the efforts of chemistry to defend the beauty of environment, represented by flowers, against every prejudice that considers chemistry an enemy of life.
