The feed solution was 15 g L^–1 PRX in acetone injected at 18 mL min^–1, and the antisolvent was pure water. A whole nickel membrane with a pore size of 40 μm was used in Methods 3 and 4. Note: Each experiment was repeated at least three times. The error bars represent one standard deviation.

Sample taken after 1 min of operation.
