%X In this
work, an inexpensive and environmentally friendly natural adsorbent obtained
from shelled (GD) and unshelled (GND) </span><span style=\"font-family:&quot;\">&lt;i&gt;</span><i><span style=\"font-family:&quot;\">Moringa oleifera</span></i><i><span style=\"font-family:&quot;\">&lt;/i&gt;</span></i><i><span style=\"font-family:&quot;\"> </span></i><span style=\"font-family:&quot;\">seeds was used for copper adsorption from aqueous
solutions. A series of experiments were performed to assess the parameters
influencing the adsorption pheno<span>menon such
as pH, adsorbent mass, adsorption equilibrium time and</span> temper<span>ature. The kinetic results of adsorption described
a pseudo-second order</span> mod<span>el. The
adsorption isotherms are satisfactorily described by the Langmuir</span> mathematical model. The thermodynamic data revealed a spontaneous and
endothermic adsorption phenomenon. The level of copper in surface water be<span>fore and after addition of moringa powders was
carried out to verify the effectiveness of the adsorbent. A maximum adsorption
rate of 51.28% and </span>61.96% was obtained with GD and GND powders
respectively. </span><span style=\"font-family:&quot;\">&lt;i&gt;</span><i><span style=\"font-family:&quot;\">Moringa oleifera</span></i><i><span style=\"font-family:&quot;\">&lt;/i&gt;</span></i><span style=\"font-family:&quot;\"> seed powders are an effective alternative for the removal of copper from
surface water.
