The cation exchange chromatographic separation of pyridine, monoethanol amine (MEA) and triethanol amine (TEA) have been explored from source to receiving phase through a fiber supported solid membrane (FSSM). The FSSM were prepared by chemical modification of cellulose fibers with introducing the carboxylic acid ion exchanging groups. The experimental values explored were concentration of pyridine, MEA and TEA (10−2 to 10−6 M) in the source solution, HCl (0.01 to 0.20 M) in the receiving phase and stirring speed (50130 rpm) of the bulk source and receiving phase. The efficiency of FSSM has been evaluated for the transport of pyridine, MEA and TEA from the source to receiving through membrane phase. The enrichment factors (EF) for pyridine, MEA and TEA from the dilute solutions such as 10−6 M observed were 1.62, 2.26 and 1.7, respectively.
