“…It was shown that the process consisted of two steps and properties of nanocomposite were mainly dependent on structure of the material. In 2005, the adsorption of catalase was studied by Shentu et al, [2] using Cibacron Blue F3GA-attached chitosan microspheres (CB-CS). Significant amount of the adsorbed CAT (up to 90.6%) was eluted in the elution medium and it revealed that CB-CS could be applied for adsorption of CAT without causing any denaturation.…”

Chitosan is an important natural polymer that occurs in the world. Chitosan is soluble in acidic aqueous media and it can be obtained in various forms. It is widely used for many applications. Hence, we briefly describe the role of chitosan in membrane form, an important area of research in which a variety of synthetic methods has been proposed and their significance is explained. Thus, this review emphasizes the papers on the high value-added applications of these chitosan membranes in diverse fields such as medicine, biological, cosmetics and nanotechnology.

“…Due to its molecular structure, featuring the presence of amino (-NH 2 ) and hydroxyl (-OH) groups, chitosan displays a high affinity for many classes of compounds and has been widely used for the removal of transitions metal ions [14][15][16][17][18][19][20][21][22][23][24][25], dyes and inks [26][27][28][29][30][31][32][33][34][35][36][37], lysozime [38], proteins [39], cholesterol [40], urea [41,42] and several other organic compounds [43][44][45][46][47][48][49]. Chitosan can also be chemically modified to produce fibers, composites and supports, improving its adsorption capacity and offering potential applications in several fields [18-24, 29, 38-44, 49, 50].…”

Abstract:The kinetics and equilibrium of Indanthrene Olive Green (IOG) adsorption on chitosan, from aqueous solutions, have been investigated. The chitosan was characterized by XRD, average degree of deacetylation (DD), TGA/DTG, IR, SEM and specific BET surface area. Batch adsorptions experiments were carried out in different pH and dye concentration. An acidic pH condition (4.0 to 6.0) was favorable to the adsorption process. The adsorption followed secondorder rate kinetics and the experimental equilibrium data followed Langmuir isotherm, suggesting that chemisorption might be the major adsorption mode. The adsorptions also occurred on chitosan fibers, being significantly lower than that of crushed chitosan. Thermodynamic parameters ( G°, H°, and S°) were calculated. The positive values of H° (161.7 kJ mol -1 ) and S° (559.9 J mol -1 K -1 ) suggest that the adsorption is endothermic and that during this adsorption process the randomness of the system increases. A simplified adsorption model is also proposed.

“…The relatively high selectivity, stability and low cost of small dye-ligands make them suitable as affinity ligands to purify proteins in large-scale purification processes [10][11][12][13][14][15][16]. Dyeligands are commercially available, inexpensive and can easily be attached, especially on matrices having hydroxyl groups.…”
