摘要：

The influence of pore sizes of nucleopore membranes and their shapes on the retention of polystyrene particles of 40-100 nm in size was studied. The interrelation between structural parameters of the nucleopore membranes found by various methods and the efficiency of filtration of calibrated particles were analyzed. The potential and limitations of the procedure for determining the efficiency of filtration of nanosized latex particles was demonstrated; the procedure was based on UV absorption spectroscopy.
