Thermodynamic and kinetic Study of Adsorption of Cobalt II Using Adsorbent of Magnesium Oxide Nano-Particles Deposited on Chitosan

The present study is on MgO nanoparticles deposited on chitosan, which is investigated for the removal of the heavy metal cobalt II using an atomic absorption spectrometer at various concentrations. The laboratory study further investigates the removal of heavy metals such as cobalt (II) by the chitosan adsorbent in the batch adsorption test system. In experiments related to this research, some parameters such as contact time, the initial dye concentration, the adsorbent amount, temperature and pH are investigated and calculated, and finally kinetic equations including (the first and the second degree) and thermodynamic equations including obedience absorption equations are studied. Likewise, Friendlich and Langmuir thermodynamic variables including ΔS, ΔG, and ΔH were examined and calculated. In this study, the effect of magnesium oxide (MgO) magnetic nanoparticles in the removal of heavy metal contaminants such as cobalt (II) is tried in vitro.
