Abstract
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 also 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, parameters such as contact time, initial dye concentration, adsorbent amount, temperature and pH are investigated and calculated, and finally kinetic equations including (first and second degree) and thermodynamic equations including obedience absorption equations are investigated, Friendlich, Langmuir thermodynamic variables including ΔS, ΔG and ΔH were investigated 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.
