Adsorption Process of Cu(II) Cations by Using the Waste of Phosphate Rock (WPR) as Novel Adsorbent material
The capacity of using WPR as an unused future adsorbent for the elimination of copper ions from synthetic watery solution was carried out in batch mode. The adsorption ability of Cu2+ by WPR was estimated in accordance with: initial concentration, time of contact, temperature and pH. The temperature...

| description | The capacity of using WPR as an unused future adsorbent for the elimination of copper ions from synthetic watery solution was carried out in batch mode. The adsorption ability of Cu2+ by WPR was estimated in accordance with: initial concentration, time of contact, temperature and pH. The temperature rise resulted a higher adsorption of Copper ions by the waste of phosphate rock (WPR). The data collected was tested by using Langmuir and Freundlich isotherms. The non-linear regression procedure was the way to obtain the parameters of adsorption isotherms. The errors analysis was finalized to find out if the model was best to adapt with the experimental protocol. In the light of the obtained results and the various previous researches carried out and published in this sense, the different conclusions were proposed about the adsorption mechanism. The thermodynamic parameters were estimated. The ΔH of adsorption was positive so the process is endothermic and ΔG was negative Therefore the adsorption was spontaneous. |
