Effecting of Temperature and Particles of Fly Ash on Copper Ion Adsorption From Aqueous Solutions

الملخص

This study examined the impact of fundamental factors that significantly influence the removal of pollutants from aqueous solutions through adsorption processes, particularly heavy metal ions. These ions can build up and remain unresolved, leading to numerous issues. This study utilized fly ash, one of the numerous natural adsorbents, to eliminate copper ions. We studied the impact of fly ash particle size and the temperature's extent on the adsorption process. We also calculated the value of free energy and enthalpy to simulate the nature of adsorption in the presence of a temperature change. The laboratory results indicated that the adsorbent's best size is the smallest size available, which is 0.075 mm, and the best temperature was 60 °C.
