Abstract

SOME cationic polysaccharide Schiff base surfactants and their …… metal complexes Ni, Cu, Fe, and Co were synthesized and their chemical structures were confirmed using FTIR, 1HNMR and UV spectroscopic analysis. The surface activities of these suractants were measured, including surface tension (), critical micelle concentration (CMC), effectiveness (cmc), efficiency (Pc20), maximum surface excess (max) and minimum surface area (Amin), interfacial tension and emulsification power at 25oC. Adsorption and micellization free energies of these amphiphiles in their solutions showed a good tendency towards adsorption at the interfaces. Also, the biocidal activity of these Schiff base surfactants and their metal complexes against bacteria (Gram positive and Gram negative) yeast, fungi and also against sulfate reducing bacteria was studied.
