Sulfated ions loaded on natural Syrian zeolite were prepared by impregnation method of zeolite samples in aqueous solution of ammonium sulfate with different concentrations. After that, the samples were dried at 1100C Followed by calcinations at 6000
C. The Characterization tests have been done of prepared catalysts using X.R.D, FTIR, TG-DTA methods and by measurement of surface aria. A new phase of sulfated elements has been formed as a result of binding SO42- ions as sulfated complex coordinated with metal elements. The catalytic activity of sample in polyethylene cracking reaction was increased directly with the percent of sulfate ions.
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.
The research was carried out at Al-Qamishli Agricultural Research Center, GSAR,
Syira, during the seasons 2011, 2012 and 2013, in order to estimate the effect of
adding different levels of a crude Zeolite (T2-20 tons/ha, T3- 40 tons/ha, in addition
to the control (without adding Zeolite T1), on wheat productivity within a bilateral
crop rotation was followed, consisted of wheat and chickpea, and on the content of
nitrogen, phosphorus and potassium in the surface layer of the soil .The research
was conducted using Complete Randomized Block Design with three replicates.
