    This paper reports an extractant screening study for the recovery of putrescine (butylene-1,4-diamine, BDA) and cadaverine (pentylene-1,5-diamine, PDA) from aqueous solutions (e.g. fermentation broths) by liquid–liquid extraction. Several extractants were studied, including 4-nonylphenol, 3,4-bis((2-ethylhexyl)oxy)phenol, di-2-ethylhexyl phosphoric acid (D2EHPA), Versatic acid 1019, di-nonyl-naphthalene-sulfonic acid (DNNSA), and 4-octylbenzaldehyde. 1-Octanol, 2-octyl-1-dodecanol and heptane were used as diluents, and temperatures of 25¿°C and 65¿°C.
