“…However, there is few literature about the adsorption of H-acid onto adsorbents, while the cost-effective adsorption technology for the industrial wastewater has been widely applied in many countries all over the world [5][6][7][8][9]. Previous researchers have made many efforts to deal with wastewater using various adsorbents, including resins, chitosan, and silica [10][11][12][13]. The adsorbents can be designed with binding sites with high selectivity and regenerated effectively, which could decrease the cost of the treatment and allow the process to be continuous.…”

“…This was confirmed in an experiment conducted by Liu et al in 2013. They stated that at degree of deacetylation lower than 85 % chitosan in barely soluble in water. Chitosan with higher DDA has more number of free amine groups available for adsorption (Mnatsakanyan et al 2013;Guibal et al 2014). …”

Heavy metals have always been the most hazardous components in the wastewater of industries like electroplating, automobiles, mining facilities and fertilizer manufacturers. Treatment of heavy metal laden wastewater requires expensive operational and maintenance systems. Food processing industries create a huge amount of shell waste which is sold to poultry farms in powdered form but the quantity thus used is still not comparable to the left over waste. The shell contains chitin which acts as an adsorbent for the heavy metals and can be used to treat heavy metal wastewater. The paper presents a study on the use of chitin and its processed product, chitosan, to remove chromium. Shake flask experiment was conducted to compare the adsorptive capacity of chitin and chitosan for chromium removal from simulated solution and isotherm studies were carried out. The studies showed that the chitosan was a better adsorbent than chitin. Both chitin and chitosan gave best adsorption results at pH 3. Chitin exhibited maximum chromium removal of 49.98 % in 20 min, whereas chitosan showed 50 % removal efficiency at a contact time of 20 min showing higher adsorptive capacity for chromium than chitin. The Langmiur and Freundlich isotherm studies showed very good adsorption capacity and monolayer interaction according to the regression coefficient 0.973 for chitosan and 0.915 for chitin. The regression coefficient for Freundlich isotherm was 0.894 and 0.831 for chitosan and chitin, respectively.

“…Adsorption is widely regarded as one of the most promising technologies because it is costeffective, little by-product, and simple operation. Biosorption has gained important credibility in recent years because of its eco-friendly nature, excellent performance, and low cost domestic technique for remediation heavily metal contaminated wastewater [12][13][14]. Cell wall of microorganisms, consisting abound polysaccharides, proteins and lipids, offers many functional groups (such as carboxylate, hydroxyl, thiol, sulfonate, phosphate, amino and imidazole groups) for the binding of metal ions [15].…”
