The shooting ranges are comprised of many valleys and rivers, so pollution easily spread through groundwater or rainwater The shooting range is difficult to access and is located in a mountainous area without any fundamental installations. Therefore, there is a limit to install purification facilities. In the soils of the shooting range, heavy metal contamination which includes lead, copper, and cadmium occurs due to fragmentation after shooting, and these are spread through adsorption, ion exchange, precipitation, and complex reaction. The heavy metal pollution can’t be decomposed naturally and remains for a long period and it is concentrated by the food chain, causing serious problems in the ecosystem. In this study, we prepared alginate-powdered activated carbon(PAC) bead and poly vinyl alcohol(PVA)-PAC complex. And reported on the study of removing lead, copper and cadmium in the water system using these adsorbents. |
