Engineering and Technology Journal, 2010, Volume 28, Issue 1, Pages 119-125

Wastes of the Iraqi date palm tree was used to study removal of heavy metal
cations ( Cu+2, Cd+2& Zn+2) from simulated artificial waste water using batch
adsorption process.
The dried parts of the date palm wastes, were grinded to ≤1mm in size and used
directly in different adsorbent / metal ion ratios, starting with metal ion
concentration of (1000ppm).
Influence of contact time, initial metal ion concentration, and adsorbent loading
weight, on removal percentage were investigated; experiments were carried out at
room temperature. 25Co and pH value of (5-6).
Date palm wastes succeeded to achieve 90% removal for Cu+2 ions, 57.5% for Cd+2
ions & 37.5% for Zn+2 ions within (60 min) contact time at adsorbent loading ratio
of 30 g/l. Removal values for mixed ions were lower due to competition
&interaction between ions, (80% Cu+2, 51% Cd+2 & 33% Zn+2 )
