Abstract

By summarizing studies of surfactants used for emulsion liquid membrane, anew polyamine-type surfactant called LMA has been developed. This type of surfactant is composed of copolymer of isobutene and isoprene in hydrophobic site and polyethylene polyamine [NH2(CH2CH2NH)(n) CH2CH2NH2, n greater than or equal to 1] in hydrophilic site. Experimental results show that the characteristics of this surfactant mainly depends on its mean molecular weight and its distribution of molecular weight, and the suitable surfactants are those with number-average molecular weight (M-n) of 5000-9000 and propermolecular weight distribution (usually M-w/M-n = 3.0-6.0).
