The effect of production parameters of crab and shrimp based chitosan on the adsorption of aluminum and lead

Heavy metals are among the most dangerous substances that cause pollution and accumulation in nature. The bio-sensitive way to decompose these pollutants is through adsorption studies with biopolymers. In this study, chitosan, one of common cost-effective biopolymers, was produced be employed aluminum lead, which have proven negative effects on living organisms. production stages shrimp crab shells were reduced three different mesh sizes deacetylation temperatures 60, 80 100 °C used. Characterizations obtained based chitosan made by using Fourier Transform Infrared Spectroscopy from results characteristic bands obtained. Adsorption carried out 20 mg.L-1 heavy metal solutions at treatment times. According determined ICP–OES analysis, for products respectively, adsorbed between 58.45% – 99.50% 23.75% 83.10%, lead 99.35% 100%, 72.80% 92.00%.
