Separation Of Copper And Aluminum Ions From Wastewater By Magnetic Microparticles

The performance of the magnetic microparticles towards the uptake of copper and aluminium ions in wastewater is characterized. The ion-exchange mechanism exists is due to the exchange of ions between the copper and aluminium ions and hydrogen/sodium ions that attached to the polyacrylic acid layer. In order to explore the ion exchange performance, the experiments are performed by varying the initial metal ion concentrations and contact time. The uptake of copper ions increases up to 80-ppm concentration and reaches pseudo-plateau at higher concentrations, while aluminium ions uptake increases as concentration increases. The time effects suggested that uptake of copper, which is higher than aluminium is due to the fact that the magnetic microparticles have more affinity towards the former ions.
