Heavy metals such as lead, copper and nickel can cause heavy metal pollution that is health hazard to human, aquatic lives and all other living creatures. Various types of peat have been shown to be effective in the removal of heavy metal from aqueous solutions. In this study, peat samples from Mukah (Block 1 and Block 7) and Kota Samarahan were characterized physically and chemically and used in the determination of adsorption efficiency and capacity of lead, copper and nickel ions from aqueous solution. In the batch equilibrium experiments, lead adsorption was the highest with 96 % removal, followed by copper with 78 % removal and nickel with 65 % removaL Peat samples from Block 7 (Mukah) showed a slightly higher adsorption capacity compared to Block 1 (Mukah) for the three heavy metal ions studied. The kinetic order for heavy metal ions adsorption by peat sample was found to be pseudo second order. Heavy metal ions adsorption by the peat samples was observed to be affected by the various factors such as adsorbent weight, particle size of adsorbent, pH of solution, initial metal ions concentration and mixed metal ions solution. The applicability of the Langmuir for heavy metal ions adsorption by the peal samples was found to be better than the Freundlich model. For the continuous column experiment, peat samples were observed to show high adsorption capacity for the heavy metals with up to 99% removal for lead and copper and 98 % removal for nickel. Results from this study showed that peat samples from Sarawak (Mukah and Kota Samarahan) have high potential to be developed as a cheap, environmental friendly and effective heavy metal ion adsorbent that is suitable for the removal of heavy metal contaminants from both potable water and wastewater.
