Abstract
Various surfactants were designed in this analysis by esterification of triethanol amine with dodecanoic acid then quaternized through benzyl bromide then complexed with hydrated cobalt chloride to produce metallocationic surfactants. Characterization of the designed surfactants by FTIR, microelemental analysis, and atomic absorption spectroscopy was done. Surface tension at four different temperatures was examined, and the surface criteria were considered which showed high surface action for the designed complexes. Free energy of micellization (ΔGomic) and adsorption (ΔGoads) were investigated. The germicidal action was checked in opposition to different microorganisms, and the results indicated that the designed complexes have high biological action.
