| Description |
The present study illustrates the potential use of hydroxyapatite (HAp) synthesized from fish scale for Cu(II) removal with optimal efficiency. Batch experiments were conducted to determine the effects of varying parameters like contact time (40–200 min), initial metal ion concentration (100–300 mg/L), and pH (2–9). The adsorption kinetics was investigated using pseudo-first-order and pseudo-second-order kinetics. The Langmuir and Freundlich isotherm equations have been also studied for the equilibrium modeling of adsorption systems. The maximum adsorption capacity of fish scale-derived HAp on copper removal is found to be 209.732 mg/g. Box–Behnken design of response surface methodology with three variables was carried out to establish a significant correlation between the effects of these parameters to the amount of Cu(II) adsorbed. The initial Cu(II) concentration 212.93 mg/L, pH 8, and contact time 40 min are also found to be optimum for sorption of Cu(II) onto Labeo rohita scale-derived HAp with removal efficiency of 91.77%.
