Syrian natural zeolit was used to study the adsorption of phenol from aqueous
solutions. Batch method was used to study the adsorption process.
The results showed that the adsorption process accurs rabidly at the first time and the
equilibrium ach
ieved after 120min .
The adsorption process performed in the rang of PH (3-10). The adsorption of phenol
increased by increasing of PH value up to(6-7) and then decreased.
The temperature affect the adsorption process and the results showed that the
increasing of the temperature leads to decreasing of the adsorption of phenol.The
maximum adsorption amount of phenol was 8 mg/g at 25C0 when the initial concentration
of phenol was 60mg/l.
Adsorption amount of phenol increased when the adsorbent dosage increased up to
0.3g of zeolite.
The resulted data of the adsorption isotherm were fitted with Langmuire model and
the monomolecular layer adsorption formed on the surdace of the adsorbent.
