Abstract

This study investigates the potential use of date-palm leaf (Phoenix dactylifera) ash as an inexpensive adsorbent for the removal of Pb (II) ions. For this purpose, the variables pH, Pb (II) ion concentration, adsorbent dosage, and temperature in the BATCH SYSTEM were investigated. The results obtained showed that the optimum pH for the removal of Pb (II) ions from aqueous solutions was equal to 5. Adsorption efficiencies obtained were 99.46, 91.47, 80.49, 69.62, 57.34, and 51.29%, respectively, for Pb (II) concentrations of 50, 100, 150, 200, 250, and 300 mg/l using 0.5 g/l of the adsorbent with a retention time of 60 minutes at 20dC. Increasing the adsorbent dosage from 0.1 to 2 g/l led to increased adsorption rate. Also, thermodynamic investigations showed that the adsorption process was dependent on temperature such that the order of decreasing removal efficiency followed the temperature order 40oC>30oC>20oC. Based on the Langmuir model, the value for the constant b was 0.152 and maximum Pb removal was 31.5%. It was concluded that date-palm leaf ash has a good potential for use as an adsorbent to remove toxic heavy metals like lead from aqueous solutions.
