Physicochemical and Antibacterial Properties of Chitosan Extracted from Waste Shrimp Shells
This research aims to study the production of chitosan from shrimp shell (Litopenaeus vannamei) of waste origin using two chemical methodologies involving demineralization, deproteinization, and the degree of deacetylation. The evaluation of the quality of chitosan from waste shrimp shells includes parameters for the yield, physical chemistry characteristics by infrared spectroscopy (FT-IR), th...
متن کاملRemoval of Congo red from aqueous solutions using nano-Chitosan
It is now recognized that adsorption using low-cost adsorbents is an effective and economic method for water decontamination. Chitosan is derived by deacetylation of the naturally occurring biopolymer chitin which is the second most abundant polysaccharide in the world after cellulose. In this study, the capacity of the chitosan nanoparticles was studied for the removal of the anionic Congo red...
متن کاملProduction and characterization of chitosan from shrimp waste
Chitosan has been produced from shrimp waste by chemical method involving demineralization, deproteinization and deacetylation. The quality of chitosan depends on the conditions of the chemical extraction process. The results showed that 3% HCI and 4% NaOH were suitable concentration for demineralization and deproteinization, respectively at ambient temperature (28±2 o C). Chitosan with a high ...
متن کاملPreparation and Characterization of Chitosan Obtained from Shells of Shrimp (Litopenaeus vannamei Boone)
The main source of commercial chitosan is the extensive deacetylation of its parent polymer chitin. It is present in green algae, the cell walls or fungi and in the exoskeleton of crustaceans. A novel procedure for preparing chitosan from shrimp shells was developed. The procedure involves two 10-minutes bleaching steps with ethanol after the usual demineralization and deproteinization processe...
متن کاملRemoval of Ni(II) and Zn(II) from Aqueous Solutions Using Chitosan
Background & Aims of the Study: The increasing levels of toxic heavy metals discharged into the environment have received considerable attention due to the adverse effects on receiving waters. Therefore, the developed adsorbent was assessed for its practical role in removal of metal ions from industrial wastewater. The purpose of the present work is to investigate the removal of Ni(II) an...
