Solubility of sulfur dioxide in chlorine-treated wastewater.

The solubility of sulfur dioxide in chlorine-treated wastewater was investigated. An experimental study was carried out to measure the solubility of sulfur dioxide in chlorine-treated wastewater over the temperature range of 10-40 degrees C. The highest solubility of sulfur dioxide was found to be equal to 1.098 x 10(-3) mole/L at 10 degrees C, whereas the lowest value of 6.17 x 10(-4) mole/L was obtained at 40 degrees C. The solubility of sulfur dioxide was correlated as a second-order dependence on temperature. The measured solubility data of sulfur dioxide in chlorine-treated wastewater were found in good agreement with that obtained using the solubility correlation.
