Chitosan wide range of application is highly dependent mainly on the presence of the reactive amino groups and its degree of deacetylation (DDA) is one of the main parameters characterizing chitosan. Chitosan was produced from deacetylation of chitin using 70% alkali concentration in an autoclave at120 o C for 1 hour. The degree of deacetylation (DDA) was determined using the acid-base titration method. A degree of deacetylation (DDA) of 70.67% was achieved from the autoclave synthesized chitosan compared to the conventional synthesized chitosan using a lower alkali concentration and temperature with a degree of deacetylation of 62.36%. In conclusion, the use of autoclave and increasing alkali concentration increased the DDA and may possibly influence other functional and biological properties of chitosan.

“…It can be effectively used for the removal of pesticides in rural areas where the pesticide contamination is prevalent [13]. Chitosan-silver nanopaticle composite was also prepared and analyzed for its pesticide removal capacity and demonstrated that microbeads of the composite are excellent agents for the removal of Atrazine from aqueous solution at neutral pH under equilibrium and column flow experimental conditions [14].…”

Bimetal oxide doped polymer nanocomposite was developed using Alumina and Iron (III) Oxide as nanoparticles with Nylon 6, 6 and Poly (sodium-4-styrenesulphonate) as polymer matrix for removal of pollutants from water. The blend sample of polymers was prepared by well established solution blending technique and their nanocomposite samples were prepared through dispersion technique during the solution casting of blend sample. The fabricated composites were characterized adopting FTIR, XRD, FESEM and EDX techniques. XRD and FESEM were used for morphological characterization of nano phase, while FTIR and EDX analysis were adopted for characterization of chemical moieties in composites. In the study of pollutant removal capacities of prepared composites, 6 % nanocomposite provided the best results. It exhibited the maximum removal of all parameters. The removal of total alkalinity was 66.67 %, total hardness 42.85 %, calcium 66.67 %, magnesium 25 %, chloride 58.66 %, nitrate 34.78 %, fluoride 63.85 %, TDS 41.27 % and EC was up to the level of 41.37 % by this composite. The study is a step towards developing multifunctional, cost-effective polymer nanocomposites for water remediation applications.
