报告四：Environmental Remediation: Case Study of Cr(VI) Removal with Nanocomposites

报告人：郭占� 教授

With the rapid industrialization, our earth faces serious pollution issues. Heavy metals have been used for different fields including painting, leathering, electroplating, electronics, etc. The left residue even at low level can cause serious pollution and give human health concerns and diseases. Among Environmental Protection Agency (EPA), Cr(VI) is very toxic and the limit for drinking water is limited to 100 ppb. The traditional methods such as aeration, sedimentation, precipitation, etc. to remove them have some drawbacks including the failure to remove the heavy metals, generation of secondary pollutants, high cost, etc. Adsorption has been reported to demonstrate some promising to achieve the required strict releasing standard. However, the conventional adsorbents show some limitations such as low rate, small capacities, etc. As a result, how to achieve effective adsorbents is becoming important. In this talk, the ways to treat the Cr(VI) is presented from aspects of materials design and synthesis. Novel nanocomposites design and synthesis will be reported to achieve the heavy metal removal.
