Chitosan is a cationic polysaccharide that is primarily derived from chitin, a natural polymer of N‐acetyl glucosamine mainly found in crustacean, insect exoskeletons and fungal cell walls, by exhaustive alkaline deacetylation to varying degrees. Chitosan has been found to have many favourable biological properties including biosafety, biodegradability and biocompatibility. These advantages make it a very promising material for diverse applications. For terrestrial animals, chitosan has been widely used as a feed additive because of its low side effects, enhancing the growth performance, improving immune functions, inhibition intestinal microbial pathogens and lowering cholesterol. Recently, it has been used as a feed additive in fish diets. Moreover, chitosan has gained an attention as an effective agent in aquaculture water treatment. A number of studies have been conducted on the effectiveness of the use of chitosan in aquaculture. Thus, the present review explored the current state of knowledge on the effects of dietary chitosan on farmed aquatic animals including antimicrobial, growth promoting, antioxidant activity and immunostimulation effects, with a particular emphasis on the optimal dose of chitosan. As well as, this review pointed out the possibility of using chitosan in aquaculture water treatment. According to the studies that were discussed in this review, chitosan is considered as a promising material with a massive potential of applications in aquaculture.

Recent Progress in Nanomaterials for Adsorptive Removal of Organic Contaminants from Wastewater

Water being most vital component of life is getting contaminated due to inhuman disposal of toxicants in water bodies. Organic compounds such as dyes, pharmaceuticals/drugs, pesticides etc. are used for various purposes and become life threatening when dumped in water bodies without pre‐treatment. Removal of these toxicants from environment is complicated but highly essential for sustainable development. Various methods have been used for this purpose among which adsorption is the most simple, fast, effective and inexpensive method for the removal of such contaminants. Nanomaterial proved to be one of the best adsorbent due to its unique structural properties which provides large surface area and high adsorption capacity. The factors affecting adsorption along with adsorption mechanism is discussed in detail. Detection of the pollutants is also quite tedious work as pollutants are present in trace quantity. UV‐Visible spectrophotometry is widely used detection technique which is easy to operate, produce accurate results and cheap. The review emphasizes the use of nanomaterial as adsorbents for the removal of various organic pollutants from wastewater using UV‐Visible spectrophotometry.

“…Nowadays, a great interest exists in identifying effective and low‐cost adsorbents that do not represent an environmental problem by themselves . Among the nonconventional materials which are being explored as potential eco‐friendly solutions for water remediation, chitosan (CS)‐based systems are receiving growing attention owing to their biocompatibility, biodegradability, relatively low cost, and high capacity and rate of adsorption of dyes and heavy metals . A recent review by Liu and Bai deals with this subject, highlighting the areas in which further efforts are needed to ensure the effective applicability of CS‐based materials in wastewater treatment .…”

Chitosan (CS) hydrogels are receiving growing attention as adsorbents for water purification purposes. The conditions of preparation of this class of materials play a crucial in the determination of their performances; however, this aspect is often neglected in the literature. In this study, we deal with this issue, focusing on the structure-property relationships of CS hydrogels obtained by phase inversion method. We show that the concentration of the starting solution determines the density and strength of intermolecular interactions, and that the gelation kinetics dictates the hydrogel structure at the microscale. Consequently, even subtle changes in the preparation protocol can cause significant differences in the performances of CS hydrogels in terms of mechanical properties and dye adsorption capacity. The observed trends are often neither trivial nor monotonic. Nonetheless, we demonstrate that they can be interpreted looking at the CS network structure, which can be inferred by rheological measurements
