The salt can be reused for extraction purposes. Anhydrous sodium sulfate is used to remove chlorinated compounds, especially polychlorinated biphenyls (PCBs) and dioxins, from a sample of contaminated soil or other material. It binds to these pollutants while most other nutrients in the soil are left alone.
