Abstract | ||||
The effective removal of heavy metals from industrial wastewater is among the most important issues for many industrialized countries. Removal of lead (II) from aqueous solutions were studied using chemical precipitation .By this method lead recovered as a white precipitate, when add the chemical basic like (Ca(OH)2, NaOH, Na (CO3)2, FeS) in varies concentration of lead solution (10,25,50) mg/L, and different pH values of solution, to reach at the optimum pH value. The precipitation efficiency for each concentration above at the optimum pH was found. From the results obtained that the lead ions were precipitated in high efficiency as, (lead hydroxide 99.6% at pH= 9.5, lead sulfate 96% at pH = 10.5 and lead carbonate 96.6% at pH = 11.2). | ||||
