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.
