영문 초록

This study was performed to improve many problems of leaching test of industrial waste sludge analysis. We analyze sludges by variation of leachant, pH and leaching time.The results were as follows: 1. As leaching at pH 5.8 by our leaching test without control of pH during leaching, the leaching rates were very low as below 1%. 2. As leaching at pH 5.8 continuously by hydrochloric acid every 2 hour, the leaching rates were higher than before 1. 3. As leaching at pH 5.0 continuously by acetic acid every 2 hour, the leaching rates were higher than 1, 2. 4. The variations of leaching rate by leaching time were smaller increase after 10 hours than before. 5. It will be recommendable that the pH of leachant maintain constantly during leaching as level of acid rain, and the acetic acid is more effective than hydrochloric acid as leachant.
