| Abstract | ||
| 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 ) | ||
