    Description / Table of Contents: Zusammenfassung Vorausgehende Untersuchungen haben gezeigt, daß nichtionische oberflächenaktive Substanzen wie n-Dodecylhexaoxyäthylen-glykol-monoäther beträchtliche Schutzwirkung Silberjodidsolen gegenüber Flokkung durch anorganische Kationen verleihen. In der vorliegenden Untersuchung wird die Wirkung der Hydrolyse flockender Kationen, Lanthan, Aluminium und Thorium, geprüft. Es wurde gefunden, daß durch die hydrolisierten Kationen die Schutzwirkung der nichtionischen oberflächenaktiven Substanz beträchtlich vermindert wird. Daraus ist zu schließen, daß die hydrolisierte Ionenart stärker als das nichtoberflächenaktive Agens adsorbiert wird und deshalb das letztere von der Oberfläche entfernt wird oder genügend große interpartikuläre Brücken, bildet, um Flockung zu verursachen.
    Notes: Summary Previous studies have indicated that non-ionic surface active agents, such as n-dodecylhexaoxyethylene glycol monoether, confer considerable protection on silver iodide sols to flocculation by inorganic cations. In the present study the effects of hydrolysis of the flocculating cations, lanthanum, aluminium and thorium have been examined. It was found that with the hydrolysed cations the protective action of the non-ionic surface active agent was considerably diminished. It was deduced that the hydrolysed species are more strongly adsorbed than the nonionic surface active agent and either displace the latter from the surface or form species which are large enough to cause flocculation by interparticle bridging.

    Description / Table of Contents: Zusammenfassung Der Einfluß von nichtionischen Detergentien auf die Bildung von negativ und positiv geladenen Silberjodidsolen mit und ohne Zusatz anorganischer fällender Ionen wurde geprüft. Die nichtionischen Detergentien waren Polyoxyäthylenglykolmonoalkyläther mit Alkylketten von 8, 12 und 16 Kohlenstoffatomen und einer konstanten Polyoxyäthylenglykolkette von 6 Einheiten. Die Detergentien scheinen die Keimbildung von Silberjodid nicht zu beeinflussen, aber sie haben einen verzögernden Einfluß auf die Geschwindigkeit des Wachstums der Solteilchen. Mit Vergrößerung der Konzentration des nichtionischen Detergens steigt die Konzentration des anorganischen Salzes, die zur Fällung erforderlich ist. Die experimentellen Ergebnisse werden mit Adsorption der Detergensmolekiile über die Alkylkette interpretiert, so daß die Athylenoxideinheiten den Grad der Solvation der Teilchen vergrößßern.
    Notes: Summary The influence of non-ionic detergents on the formation of positively and negatively charged silver iodide sols in the presence and absence of inorganic flocculating ions has been examined. The non-ionic detergents used were polyoxyethylene glycol monoalkyl ethers with alkyl chains of eight, twelve and sixteen carbon atoms and a constant polyoxyethylene glycol chain of 6 units. The detergents did not appear to influence nucleation of silver iodide but had a retarding effect on the rate of growth of the sol particles. As the concentration of non-ionic detergent was increased the concentration of inorganic salt required to produce flocculation also increased. The experimental results were interpreted in terms of adsorption of the detergent molecule, via the alkyl chain, so that the ethylene oxide units increased the degree of solvation of the particles.
