Abstract
In this study, different metallocationic surfactants were prepared by reaction of N,N dimethyl ethylene diamine with benzaldehyde (Schiff base reaction) then quaternized the resulted tertiary amines with different alkyl halides such as dodecyl bromide and hexadecyl bromide to produce a series of quaternary ammonium salts. Finally, complexing the cationic surfactants with stannous chloride and cobalt chloride to give the corresponding metallocationic surfactants. Surface tension of these surfactants at four different temperatures was investigated. The surface and thermodynamic parameters were studied. FTIR spectra were done to confirm the structure of the compounds and their purity. The antimicrobial activity of the prepared complexes was determined via the inhibition zone diameter against different microorganisms also against sulfate reducing bacteria by the dilution method. The results indicate that these metallocationic surfactants have good surface properties and good biological activity on different microorganisms.
