Abstract

This research delves into the application of backwater crustacean-derived biochitosan (BCS) as a bio-adsorbent for the synthesis of chitosan and its subsequent use in removing Cu (II) ions from wastewater, particularly within the metal finishing industry. The physical and chemical surface morphology of the synthesized material was thoroughly examined through various characterization analyses, affirming the fine structure of the produced biochitosan (BCS). The study further explores the optimization and modeling of adsorption conditions using response surface methodology (RSM) and response optimizer (RO) in Minitab Software. Additionally, the study employed the Box-Behnken method in Minitab Software to optimize the analyzed parameters and response surface morphology. The overall findings underscore the potential of biochitosan as an environmentally friendly and effective bioadsorbent for the removal of Cu (II) ions from industrial wastewater. This investigation not only contributes to the field of bio adsorption but also provides valuable insights into the optimization and surface characteristics of the synthesized material. The optimized conditions for maximum Cu (II) ion removal efficiency were determined as follows: solution pH of 6.0, biochitosan dosage of 0.15 g L-1, and Cu (II) ions concentration of 25.35mg L-1, resulting in an impressive removal efficiency of 72%. The batch adsorption experiments and optimization results exhibited a linear correlation, reinforcing the reliability of the obtained data. The removal efficiency of divalent copper ions using the synthesized chitosan was found to be 72% under optimum conditions.
