“…As anionic dyes interact with either cationic polymer groups or directly to fibers they have been widely employed in natural fiber dying including wool, cotton and silk. 86,101,102 In order to address these environmental issues, various natural and synthetic materials have been employed for remediation of water and industrial wastewater polluted with dyes by applying adsorption processes. 103 Other widely applied methods for remediation of water and industrial wastewater polluted with dyes include ion exchange, 104 Unlike the solid adsorbents, the polysaccharide-based hydrogels appear as excellent tool for the removal of aqueous solutes, including dyes and pigments, 103,113 Among various types of polysaccharide hydrogels, those ones based on chitin-and chitin-derivatives are promising adsorbents for the adsorption, removal and separation of anionic and cationic dyes from aqueous solutions.…”

Resumo: Nosso objetivo é mostrar e discutir os dados mais relevantes sobre a abordagem de síntese e a caracterização de hidrogéis à base de quitina e derivados de quitina, como a quitosana, bem como suas aplicações em diversas tecnologias de materiais. A relevância atual e futura dos materiais à base de quitina, quitosana e derivados foi verificada pelo impressionante número de publicações científicas e tecnológicas (tanto papéis como patentes) que aparecem no dia-a-dia. Os hidrogéis, que apresentam propriedades semi-líquidas e semi-sólidas, tornaram-se uma grande promessa para aplicações onde o uso eficiente da água é essencial para melhorar as propriedades físico-químicas dos solos áridos. Eles também são eficazes no tratamento de águas contaminadas com corantes, chumbo cádmio, mercúrio, níquel e assim por diante, minimizando o impacto ambiental. Palavras-chave:Hidrogel; polissacarídeo; polímero superabsorbente; condicionador de solo; recuperação de água. AbstractOur purpose is to show and discuss the most relevant data on the synthesis approach and the characterization of hydrogels based on chitin and chitin-derivatives, such as chitosan, as well as their applications in several materials technologies. The current and future relevance of materials based on chitin, chitosan and derivatives have been verified by the impressive number of scientific and technological publications (both papers and patents) that appears day-by-day. The hydrogels, which show half liquid-like and half solid-like properties, have become a great promise for applications where the efficient use of water is essential to improve the physical-chemical properties of the arid soils. They are also effective in treatment of waters contaminated with dyes, lead cadmium, mercury, nickel, and so on, minimizing the environmental impact.

“…At pH greater than 7, the hydrogel surface carries negative charges because of the partial hydrolysis of amide functionalities. MB is a cationic dye, so, there is a strong electrostatic attraction between the MB and hydrogel which leads to increase in the adsorption . The schematic interactions of dyes are shown in Figure .…”

“…The results are shown in (Figure ). These results may be explained on the basis of the weaker interaction between the dye and the hydrogel due to the deprotonation and protonation of the charged groups present in the hydrogel backbone …”

A novel hydrogel poly(acrylamide‐co‐poly‐N‐methylacrylamide) grafted katira gum (KG) was synthesized via free radical copolymerization using a mixture of acrylamide and N‐methylacrylamide in presence of N,N′‐methylene‐bis‐acrylamide as a crosslinking agent. A series of hydrogels (KG‐1 to KG‐6) were prepared by varying amount of acrylamide and N‐methylacryamide. Poly‐acrylamide‐g‐katira gum (PAM‐g‐KG) and poly‐N‐methylacrylamide‐g‐katira gum (PNMA‐g‐KG) hydrogels were also prepared using same crosslinking agent. Swelling characteristics of all the prepared hydrogels in water were evaluated and the hydrogel with best swelling property (KG‐6) was identified. The hydrogel KG‐6 was characterized by FTIR, X‐ray diffractometer, and scanning electron microscopy and was used for the adsorption of textile dyes namely methylene blue (MB), malachite green (MG), and congo red (CR) from single and ternary solutions. Adsorption dynamics, kinetics, isotherm, and thermodynamics of all the prepared hydrogels were studied in the ternary dye solutions. The sorption kinetics data were fitted well to pseudo‐second order and the equilibrium adsorption data were found to follow Freundlich isotherm model. The thermodynamics studies showed that the adsorption process was spontaneous and exothermic in nature. The preferential dye adsorption by the hydrogel was followed in the order MB > MG > CR. © 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 45958.
