Abstract

The outer bark of the plants, Eucalyptus deanei (Mountain Blue Gum), Lophostemon confertus (Brush Box) and especially Melaleuca quinquenervia (Paperbark) have been found to be capable adsorbents of total arsenic from fly ash leachate. The leachability of arsenic from two acidic and one alkaline class F fly ashes was investigated using batch leaching at room temperature. The effects of pH, solid:liquid ratio and leaching time were examined. Batch adsorption experiments were carried out using the E. deanei, L. Confertus and M. quinquenervia bark as the adsorbent for total As removal from synthetic solutions under various conditions. It was observed that M. quinquenervia bark has the highest capacity for arsenic removal compared to the other species. Up to 100% of arsenic was removed from fly ash leachates after 24 hours using 20 g L-1 M. quinquenervia bark at pH 11.
