Abstract—One of the serious subjects of recent discussions of environment problems is pollution of underground water, surface water and river water by toxic heavy metals. The issue is critical in that it destroys the surrounding environment and even affects human beings. There is a recent study that reported that drinking of water polluted with arsenic can cause serious health problem. However, as the arsenic (As) can exist in various shapes according to the environmental characteristics and is highly migratory, it is not easy to purify the water contaminated by arsenic, and there are few studies of it. As such, this study used the adsorption method to remove the arsenic. Based on the fact that the adsorption can quickly remove and strongly adsorb the pollutants, it intended to examine the efficiency of removing arsenic using the activated alumina gel which is one of the adsorption media. The test result indicated that more than 80% of arsenic in an aqueous solution was removed within 24 hours and more than 95% of arsenic was removed when the aqueous solution was continuously observed for about one week. The result confirmed that the activated alumina gel was the outstanding medium to be used as the absorbent.
