This research aimed to study the ability of both reeds (Phragmites
communis) and poplar trees (Populus nigra V.hamui) to accumulate
Pb and Cu. Where speared naturally prevail on the sides of the
Rumaila River in Jableh town (research site), during 2014-2015.
The possibility to develop a High-Performance Liquid
Chromatographic method was studied for simultaneous
determination of: Cu(II), Ni(II), Co(II), Hg(II) by using DTC as
reagent. The diethyldithiocorbamate Reagent was studied by
spectrophotometric Method, Unique Ionisation Constant was
determined and its value.
We present in this study accumulate of two heavy metals (Fe - Cu) in the tissues of
flowers , leaves , stems and roots of Lamium moschatum Mill.
The study showed that the plant accumulated (Fe - Cu) in different concentrations ,
with an increase i
n the concentration of (Fe) in all samples specially in roots . The highest
concentration of (Cu) was in flowers (1669.23 mlg/kg) , and for (Fe) was in roots (4539.5
mlg/kg) .
The results showed a convergency in the concentrations of (Cu) in the parts of plant
for the same sample (432.62 - 490.75 - 353.409 - 272.73 mlg/kg) in flowers , leaves , stems
and roots in order . but the concentrations of (Fe) in roots was higher than that in flowers ,
leaves and stems for the same sample .
In sample -5- the value of (Fe) in roots was (1124.91 mlg/kg) but in flowers , leaves
and stems at the same sample was ( 234.83 - 218.82 - 205.24 mlg/kg ) in order.
