Table 1 The extraction efficiency (E) and enrichment factor (Ee) values of polyamines after flat sheet supported liquid membrane extraction from different volume of urine samples. The pH of urine was 7 and acceptor was 1 M HCl. Donor phase polyamines concentration was 50 μM. CV – coefficient of variation
