Ethylenediamine modified date palm trunk an attractive approach for improvement of lead (II) uptake from aqueous solutions. Factors influencing Pb(II) adsorption onto MDPT such as initial Pb (II) concentration, pH, contact time, and adsorbent dosage were investigated. The adsorption equilibrium was established within 120 min. Before and after adsorption, MDPT was characterized by Fourier transform infrared spectroscopy (FTIR). The results showed that the pseudo-second order model fits the experimental data very well. The equilibrium data have been analysed using Langmuir and Freundlich isotherm models. The recovery of Pb(II) adsorbed on MDPT was found 98.5% using 0.2 M HCl. Desorption experiments showed the feasibility of the regeneration of MDPT.
