Abstract

The effect of charcoal adsorbability on the contents of heavy metal ions, including Cr, As, and Cu, in water, as well as the fish liver, gill and scales after the time variation of wood preservatives CCA and ACQ in water were evaluated. The time-dependent pH value of charcoals in water with different preservatives was 7.97-8.59. Bamboo charcoal had better adsorption for the Cu content, but for the Cr and As contents it had poor adsorbability. Bamboo activated carbon had preferable adsorption for both Cr and Cu contents, yet it had insignificant adsorbability for the As content. The Cr ion content in the fish scales was with a decreased tendency and the Cu ion content in the fish liver was decreased due to the charcoal adsorbability. However, the Cr ion content in the fish liver and gills was no significant difference before and after a period of time. For the As ion content in fish liver, gills, and scales, there were no obvious change. According to the water quality result, the Cu ion content was decreased slightly, but the As ion content was increased slightly and higher than Cr ion content. In the scope of this study, the charcoal adsorbability can prevent water environments from acidifying, and the Cr and Cu contents can be adsorbed, as well as the adsorbability of bamboo activated carbon was better than that of bamboo charcoal.
