Abstract

In this study, a novel adsorbent was prepared, namely alginate and mangrove composite beads coated with chitosan (AMCBCC), and performed well to remove heavy metals and residual oil from palm oil mill effluent (POME) using continuous adsorption studies in a fixed bed column under different bed heights. Thomas and Yoon–Nelson models were applied to predict the breakthrough curve and to compute the characteristic parameters such as maximum capacity and the time required for 50% of adsorbate breakthrough. It was found that the total removal percentage of iron ions, zinc ions, and residual oil were 26.75%, 76.74%, and 83% respectively at pH 3, and a bed height 27 cm. Both models can well describe the breakthrough curve of heavy metals and residual oil. These results indicated that AMCBCC can be used to remove heavy metals and residual oil from industrial wastewater.
