Determination of concentration changes on membrane surface as function of time during evaporation of reverse‐osmosis film casting solutions

摘要

AbstractData on the activity of acetone for the binary system acetone‐formamide, and a specific ternary system cellulose acetate‐acetone‐formamide are given for the temperature range 0 to 30°C. A method of determining concentration changes occurring on the membrane surface during the evaporation stage in the process of making cellulose acetate reverse osmosis membranes is illus
