Natural zeolite which named TS-14 from Tel- Asis area in Syria has beenstudied.
The sample was crashed under fixed force, 5kg/cm2 and sieved with differentsizesieves.
The product was divided to five samples with different size, andnamedTS-14-1,<0.1
25mm,
TS-14-2, 0.125-0.3mm, TS-14-3, 0.3-0.6mm, TS-14-4, 0.6-85mm, TS-14-5, 0.85-1.4mm.
The specific surface area was calculated. The maximum specific surface area was
84.6m2/g for the first sample which has minimum size, then the value of surface area
decreases to become 54.2m2/g for the second sample, therefore the value of surface area
increases for third and fourthsamples to became 60.3m2/g and 66.3m2/g, respectively.
The adsorption of the Ni(II) ions was studied using the samples. The capacity of the
samples is increasing when the granule size is increasing, and the maximum capacity was
91.7mg/g as Ni(II) ions for last sample. The adsorption process of Ni(II) ions takes place
on the heterogeneous centers.
This research focuses on determination the concentration of some heavy metal
elements (Nickel Ni and Cadmium Cd) in the coastal water sediments of Ras Al-Basit
(Latakia ) during the period that range between Autumn 2013 and Summer 2014 using the
A
tomic Absorption (Atomic Absorption Spectrophotometer: AAS) at two different (closed
and open) geographical regions.
The results of the research indicate a correlation monumental between the change in
the concentration of studied metallic elements (Ni & Cd), the quality and sediment
sampling sites on the one hand, and the sources of pollution on the other. It observed the
rule of fine sand with minor amount of clay in the sediments collected from closed area;
with high concentrations of both Nickel (755.50mg/Kg), and Cadmium (71.30μg/ Kg),
compared with the open area while the majority of the sediments are medium sand with
low Nickel and Cadmium concentrations (38.85mg/Kg; 13.31μg/ Kg).
