Abstract

In this paper different amine alginate salts were prepared by neutralization of alginic acid with amine compounds (triethanol amine, tri-isopropanol amine and hexamine). The chemical structures of the prepared compounds were confirmed using Gel Permeation Chromatography (GPC) and Fourier Transform Infrared Spectroscopy (FTIR). The surface properties of the target surfactants were studied and the surface parameters were determined; including surface tension, critical micelle concentration, maximum surface excess and minimum surface area, with and without addition of dodecytrimethyl ammonium bromide as a co-surfactant. Finally, the standard free energies of micellization and adsorption of the prepared surfactants were calculated. The obtained results indicated that, the adsorption activity of the three prepared alginate salts had increased by addition of very low concentration (0.0005 m/L) of DTAB surfactant, owing to the formation of an electrostatically stabilized Surfactant-Polyelectrolyte Complex.

Kurzfassung

In dieser Untersuchung wurden verschiedene Aminalginate durch Neutralisation von Alginsäure mit Aminen (Triethanolamin, Triisopropylamin und Hexaamin) hergestellt. Die chemische Struktur der synthetisierten Verbindungen wurde mittels Gelpermeationschromatografie (GPC) und Fourier-Transformations-Infrarot-Spektroskopie (FTIR) bestätigt. Die Oberflächeneigenschaften der Tenside wurden studiert und die Oberflächenparameter wie Oberflächenspannung, kritische Mizellbildungskonzentration, maximaler Oberflächenüberschuss und minimaler Platzbedarf an der Oberfläche in Ab- und Anwesenheit des Cotensids Dodecyltrimethylammoniumbromid bestimmt. Letztlich wurden die Freien Standardenergien der Mizellenbildung und Adsorption berechnet. Die erhaltenen Ergebnisse zeigen, dass die Adsorptionsleistung der drei synthetisierten Alginate bei Addition von DTAB in geringen Konzentrationen (0.0005 m/L) aufgrund der Entstehung eines elektrostatisch stabilisierten Tensid-Polyelektrolytkomplexes zunimmt.

Key words: Alginate salts; surfactant-polyelectrolyte complexes; mixed surfactants; co-surfactants
