چکیده مقاله:

The wastewater of textile industries possesses toxic materials that it is needed to be removed before discharge into the environment. Several methods for dye removal from of textile plants are used. Adsorption is the most effective between these methods. In the study, Olive Kernel has been applied for dye removal. Methylene blue was selected as test probe. The experiments were carried out in a bench scale using batch system. The effect of various parameters such as initial dye concentrations (25-150 mg/L), adsorbent dosage (0.10-0.50 g), contact time (10-70 min) and the solution pH (2.0-12.0) on the removal of dye were investigated. The results indicated that the increase in adsorbent dose led to increasing of the removal efficiency. According to the results, adsorption efficiency was increased with increasing of pH and exposure time. Higher removal was observed with increasing of pH toward alkaline conditions. In order to evaluate the suitability of the introduced bioadsorbent for dye removal, isotherm and kinetic investigations were also performed. The results obtained showed that olive kernel is a cost effective and efficient adsorbent that can be applied for dye removal successfully
