Ultrafiltration Membranes: Pore Structure Characterization by Liquid-Liquid Porometry

摘要

Liquid-Liquid Porometry has been discussed. It can measure through pore throat diameters, mean flow pore diameter, the largest pore diameter, and pore distribution and liquid permeability of ultrafiltration membranes. Although through pore throat diameters are measurable by capillary flow porometry, the liquid-liquid porometry test pressures are almost an order of magnitude less than those used in capillary flow porometry.
