Abstract
AbstractIn this article we show steps taken toward the development of bactericidal and fungicidal synthetic cationic surfactants by the reaction of decyl, dodecyl or tetradecyl amine with selenious acid to produce a series of quaternary ammonium salts which consequently converted to copper and cobalt cationic complexes via complexing them with copper (II) or cobalt (II) ions. Surface properties of these surfactants were investigated. The surface properties studies included critical micelle concentration (CMC), maximum surface excess (Γmax) and minimum surface area (Amin). Free energy of micellization () and adsorption () were calculated. The antimicrobial activity was determined via the inhibition zone diameter of the prepared compounds measured against five strains of a representative group of microorganisms. FTIR spectra, elemental analyses and 1 H‐NMR spectra were obtained to insure the purity of the prepared compounds
