Saleh PY - 2022 VL - 63 IS - 8 SP - 3251 EP - 3263 JO - Iraqi Journal of Science المجلة العراقية للعلوم SN - 00672904 23121637 AB - In batch experiments, a natural chitosan adsorbent was employed to extractcobalt ions from industrial wastewater under varied parameters of startingconcentration, adsorbent weight, pH, and contact duration. The adsorbent wasexamined using FTIR, XRD, and AFM. For an initial cobalt ion concentration of5x10-2 mol/l at pH 6, time 35 minutes, temperature 25 °C, and adsorbing dose 0.1 g,the results showed a maximum removal percentage of 99.0 percent. The Freundlichisotherm and the pseudo-second order kinetic model both suit the experimental datawell. According to thermodynamic studies, the process was spontaneous andendothermic.
