Sulfur dioxide absorption and desorption by water drops ...

Dec 15, 2001  A new model is developed for the absorption and desorption of sulfur dioxide by drops falling through air containing a low concentration of it. The model predictions are compared with published experimental results. We observe that whatever the type of absorption or desorption experiments is, the present model fits the experimental results.

The Absorption of Sulfur Dioxide by Fruit Tissue - McBEAN ...

Absorption rate was affected appreciably by type of fruit, surface area as influenced by size, and the use of irrigation, and less so by variety and maturity. Sulfur dioxide uptake through the skin was slow. Combinations of gas concentration and exposure time were the most important processing variables affecting absorption.

Sulphur Dioxide - an overview ScienceDirect Topics

May 21, 2008  Absorption of sulfur dioxide is concentration-dependent, with 85% absorption in the nose at 4–6 μg/m 3. For common ambient concentrations of sulfur dioxide, absorption in the upper airways may be inefficient and increased flow rates reduce the percentage of inspired sulfur dioxide absorbed in the nose and upper airways, thus physical ...

Selective Sulfur Dioxide Absorption from Simulated Flue ...

Hollow fiber membrane contactors (HFMCs) provide a large specific surface area. Thus, their significantly reduced volume provides an advantage compared to the conventional gas–liquid contactor. In this study, the selective removal efficiency of flue gas, in which sulfur oxide (SO2) and carbon dioxide (CO2) coexist, was measured using a polypropylene (PP) HFMC with such advantages.

Abstract. Cotton plants were grown in nutrient solutions containing 0.1, 2, 5, 10, and 50 ppm. sulfate. Atmospheric sulfur dioxide was excluded from the roots and the sulfate in the nutrient solution was labeled with S35 to permit determination of the amount of sulfur which was absorbed by the plants directly from the atmosphere.
