Removal of kerosene from waste water using Iraqi bentonite

الملخص EN

The aim of the present research is to stud the potentiality of Iraqi betonies as adsorbent for removing of kerosene from wastewater.

Also the capacity of betonies for kerosene removal was compared to the activated carbon capacity.

The sorption of kerosene onto betonies and AC.

were described by two well–known adsorption isotherm models namely Langmuir and Freundlich models.

It was found that the Freundlich model can fit very well the equilibrium isotherm adsorption of kerosene onto betonies and AC.

Batch experiments were carried out to study the effect of adsorption of kerosene onto betonies using various conditions such as initial concentrations of kerosene (100-500 ) mg / L, agitation speeds (125, 250, 500, 800) RPM, and weights of betonies (0.05, 0.5, 1.1) gm, particle sizes (0.5- 0.6) mm, and temperature 303 k.

It was found that the best results for removing kerosene onto betonies were obtained at C˚ = 500 mg / L, RPM = 800.

Activated carbon was used as powder and granular of particle sizes ranged (1-1.

18) mm and (0.

5-0.

6) mm.

The results indicated that the activated carbon was more active than betonies for removing of kerosene from wastewater.
