Activated carbon fabrics volume average pore

Figure I. Activated Carbon Fabric Adsorption Capacity for HD and CEES V5. Volume Average Pore Diameter...

Off-gassing tests were performed with 1.75 in (4.5 cm) diameter discs of the following Calgon Zorflex activated carbon fabrics 50K knitted fabric, 100 micro woven fabric, and 100 meso woven fabric. The volume average pore size and specific surface area of each of these fabrics are as follows ... 

The adsorption capacity of activated carbon fabrics for CEES and HD dissolved in HFE-7100 increases with the specific surface area and as a function of the the volume average pore diameter, over the range of 0.2 nm to 2.9 nm. There is an excellent correlation between the HD adsorption values and the CEES adsorption values. Fabrics with a high mesopore concentration will exhibit significantly more liquid phase capacity for CEES and HD than microporous fabrics. Negligible off-gassing of CEES or HD is observed from activated carbon fabrics at low contaminant loadings when the contaminant is contained within the pores of the fabric.
