摘要：
Physicochemical properties of ultrafiltration membranes were studied by scanning electron microscopy. The membrane elemental composition (carbon, oxygen, and sulfur) was determined by energy dispersion analysis. The elements were shown to be homogeneously distributed along the membrane. A homogeneous pore distribution on the membrane surface was found after covering it with a thin gold layer. The pore sizes are ∼50 nm. The topographic analysis of the permeate-side of the membrane indicated its anisotropy.
