ABSTRACT:
An agent is disclosed that is useful for treating liquid media, e.g., dechlorinating aqueous media. The agent contains at least one salt from the sulfur oxide family, such as sodium sulfite. In the agent, the salt is in mixture with an organic gel forming binder. The mixed material is especially adapted for preparing self-supporting, discrete particles of solid compacted material, e.g., tableted composition. The composition can provide such compacted material not only of desirable strength and hardness, but also of desirably controlled dissolution rate.
