Evapoporometry: An Effective Analytical Technique for Membrane Pore Size Characterization of Hollow Fiber Membranes
Date of Graduation
Bachelor of Science in Chemical Engineering
A new analytical technique called evapoporometry has shown to be an effective and inexpensive method for membrane pore size characterization. This technique is based on the correlation between vapor pressure and pore size as described by the Kelvin equation. Evapoporometry has many advantages over tradition pore size characterization techniques. This technique allows for large sample sizes, uses minimal equipment, is capable of analyzing membranes within a wide range of pore sizes, and provides a highly descriptive representation of the pore distribution. This research looks at the application of evapoporometry as a technique for characterization of hollow fiber membranes. Using the theory for evapoporometry of flat sheet membranes and a modification to the diffusion chamber, this technique was successfully applied to hollow fiber membranes.
