There is significant interest in developing novel absorbents for hazardous material cleanup. Hazardous materials, including strong acid/bases, oils, and solvents, are widely used in manufacturing industries. Spillages of these hazardous materials have devastating consequences for both human health and the environment. Thus, industries have made efforts to appropriately treat hazardous materials after use. Many approaches for hazardous material cleanup have been proposed. However, most previous studies have focused on synthesizing hydrophobic absorbents to remove oils and organic solvents. Relatively little attention has been paid to hydrophilic absorbents that can remove aqueous hazardous materials. We report an iron oxide/sponge absorbent that can absorb a strong acid/base solution without an additional force/absorption delay/overflow, generate fewer dust particles than the level of a clean room (class 100), and prevent the formation of droplet fragments during solution drop tests. |
