Students should dispose of solid anhydrous sulfate, such as anhydrous sodium sulfate, by placing it in a designated, labeled waste container and then having it collected and disposed of by a licensed waste disposal contractor. It should not be poured down drains or sinks, as solid forms must use other disposal routes rather than sewer disposal systems
. Additionally, care should be taken to keep such solids away from drains, surface water, and groundwater to prevent contamination
. Laboratory protocols typically require solid chemical wastes to be handled through proper hazardous waste disposal channels rather than regular trash or drain disposal
. In summary:
- Sweep or vacuum the solid anhydrous sulfate carefully.
- Place it in a labeled waste container.
- Arrange for disposal through a licensed chemical waste contractor.
- Do not dispose of solid anhydrous sulfate down sinks or drains.
This ensures compliance with safety and environmental regulations and prevents pollution
