flocculation of cu, zn, pb, ni and mn during mixing of talar river water with caspian seawater
نویسندگان
چکیده
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.

متن کاملflocculation of cu, mn, ni, pb, and zn during estuarine mixing (caspian sea)
during estuarine mixing of fresh water with saline water and due to the flocculation process, aportion of dissolved metals come into particulate phase, and the dissolved load decreases. this process plays an important role in self-purification of heavy metals in rivers. in this study, flocculation of cu, mn, ni, pb and zn during mixing of cheshme-kileh river water with caspian sea water has bee...
متن کاملRole of estuarine natural flocculation process in removal of Cu, Mn, Ni, Pb and Zn
The flocculation of dissolved heavy metals is a process which has an important effect on decreasing the concentration of the colloidal elements during estuarine mixing of river water and sea or ocean water. During this important process, a large amount of colloidal elements change into particles in the form of flock and the dissolved loads decline. This study is performed to evaluate the mechani...
متن کاملStudy of trace metals during estuarine mixing of Jarahi River water with the Musa Estuary water
Flocculation of metals is one of the most important estuarine processes that occur due to the mixing of seawater and river water and colloidal metals undergo this process come in the form of flocculants. Due to the important role of flocculation process in producing suitable food sources for aquatic organisms and reducing the amount of input pollution into aquatic environments, the present stud...
متن کاملan investigation of self-purification of heavy metals during mixing of river water with sea water
estuaries are considered as highly dynamic ecosystem that include the mixing or transition zone between river freshwater and saline water from oceans and seas. estuaries are very important aquatic systems by preserving the coastal biota. flocculation of metals during mixing of freshwater with saline water can be considered as the most important estuarine processes. due to flocculation process, ...
متن کاملAn investigation on role of salinity, pH and DO on heavy metals elimination throughout estuarial mixture
One of the most paramount processes that play a considerable role in reducing the concentration of heavy metals during estuarine mixing is flocculation. Not only does such a process cause a huge percentage of metals to come into the particulate phase, but also it provides ample nutrients for the aquatic life. In the present study, impact of such factors as salinity, pH and DO on flocculation of...
