reached 80.34% at 100 mL/min. However, the percentage of
amoxicillin extraction and stripping decreased with an increase
of the flow rates of feed and stripping solutions due to resident
time of solutions in the hollow fiber module [45]. Moreover,
Leepipatpaiboon et al., [48] reported that higher flow rates can
cause the liquid membrane to leak out of the micro-pores of hollow
fibers and destroy the liquid membrane system.
