Attempting to Characterize the Sink Effect in a Small Stainless Steel Test Chamber

Source

Small environmental test chambers may present wall adsorption for volatile organic compounds (VOC), which must be known for correct emission or adsorption rate determinations on indoor materials. Experiments in a 0.28 m3 stainless steel chamber, in the dynamic (air flow through the chamber) and static mode (no flow), with n-decane and n-dodecane are described. Further experiments with a 0.45 m3 glass chamber and more compounds are reported. The concentration versus time data were used as input for a new mathematical model with two sink compartments (“two-sink” model), which is described. The model provides a much better regression of data points than the previous “sink” model. The two sinks show greatly different rate constants. The model provides a reasonable description of the mass balance in adsorption-desorption experiments.
