초록

For the safe disposal of the end used CCA treated wood, the biological method was studied. Aspergillus niger has been known to be grown on the fresh wood surfaces even on the CCA treated wood surface. Therefore, in this study we estimated the removal efficacy of heavy metals from CCA treated wood by A. niger. The selected fungi, A. niger adsorbed the heavy metals from CCA solution. A. niger removed 95% of arsenic, 55% of copper, and 23% of chromium. From these results, A. niger appeared to be useful for the removal of chromium, copper, and arsenic from the end used CCA-treated wood and the use of A. niger-alginate could be effective.
