Abstract
The ability of undyed and dyed coconut pollens to remove Cu(II) and Zn(II) from single ion solutions was been studied. The experiments were carried out using coconut pollens (1.0 g) undyed coconut pollens, UDCP, and dyed coconut pollens, DCPI, DCPII and DCPIII of different particle sizes: 0.40, 0.63 and 0.80 mm, respectively. The amount of Cu(II) adsorbed on UDCP, DCPI, DCPII and DCPIII were 69.20, 97.90, 94.70 and 93.10%, respectively, while that of zinc adsorbed on these adsorbents were 87.15, 98.30, 92.55 and 90.05%, respectively. These results show that dyed coconut pollens is effective in removing Cu(II) and Zn(II) from aqueous solutions.
