Summary

Carey Leas silver sol is investigated with electron microscopy and analytical methods. Its colloidal behaviour is studied. Coagulation, repeptization and fractionation are described. TheCarey Lea sol is not a protected colloid. It consists of small (80 Å diameter) spherical, rather monodisperse, positively charged silver particles. Citrate ions are adsorbed at the particle surface in superequivalent adsorption.

Zusammenfassung

DasCarey Leasche Silbersol wurde untersucht mit den Methoden der Elektronenmikroskopie und der chemischen Analyse sowie nach seinen kolloidchemischen Eigenschaften. Flockung. Repeptisation und fraktionierte Koagulation werden beschrieben. Es stellt sich heraus, daß das Sol aus feinkörnigen (80 Å Durchmesser), kugelförmigen, ziemlich monodispersen, positiv geladenen Silberteilchen besteht, an denen Zitrationen, in superäquivalenter Adsorption angelagert sind.
