Abstract

A study was conducted in the collage of agriculture/ University of Baghdad- Abugraib the alternative location for the University of Anbar during the spring 2017, to evaluate. the impact of pH on heavy metals concentration (Cd+2, Pb+2 and Cu+2) in sewage, eight different pH values were prepared (7.5, 8.0, 8.5, 9.0, 9.5, 10.0, 10.5 and 11.0) or each studied metal which has to be added to the sewage with concentration of 100 mg. L-1. Solutions were shaked and filtered using filter paper, and the metal concentration was measured using the Atomic Absorption Spectroscopy. Obtained results presented that rising sewage pH led to reduction of heavy metals concentration, highest reduction was for the two elements cadmium and couplet where their concentration decreased to 55% at pH of 11.0, while the copper gave 53% at the same pH value for sewage.
