Flocculation of Cu, Zn, Pb, Ni and Mn during mixing of Talar River Water with Caspian Seawater
Karbassi, A. R.; Nouri, J. & Ayaz, G. O.
Abstract
In the present investigation flocculation of dissolved Cu, Zn, Pb, Ni and Mn in a series of mixtures with salinities ranging from 1.5 to 9.5% during mixing of Talar river water with the Caspian Sea water was studied. The flocculation trend of Zn (87.22%) >Mn (45.31%) >Pb (39.09%) >Cu (36.58%)>Ni (12.70%) indicates that Cu, Zn, Pb and Mn have non-conservative behavior and Ni has relatively conservative behavior during estuarine mixing. Highest flocculation of metals occurs between salinities of 1.5 to 3.5%. Statistical analysis indicates that the flocculation of studied metals except for Ni is governed by pH and total nitrogen.
