Beschreibung

(30,5 x 23 cm). Moderner Pappband, unbeschnitten. Erste Ausgabe seiner grundlegenden, in den "Bakerian Lecture" erschienenen Arbeiten, in denen er die Resultate seiner auf Diffusion von Flüssigkeiten gegründeten dialytischen Trennungsmethode beschreibt. "Although some isolated investigations on colloids had been carried out before Graham, his publications in this field laid the foundations of colloid chemistry. In 'On the Diffusion of Liquids,' Graham applied to liquids the exact method of inquiry he had applied to gases twenty years before, and he succeeded in placing the subject of liquid diffusion on about the same footing as that to which he had raised the subject of gaseous diffusion prior to the discovery of his numerical law. He showed that the rate of diffusion was approximately proportional to the concentration of the original solution, increased with rise in temperature, and was almost constant for groups of chemically similar salts at equal absolute (not molecular) concentrations and different with different groups. He believed that liquid diffusion was similar to gaseous diffusion and vaporization with dilute solutions, but with concentrated solutions he noted a departure from the ideal relationship, similar to that in gases approaching liquefaction under pressure" (DSB). - Graham, der zu den Begründern der Kolloidchemie gehört, unterscheidet daher zwischen Kolloiden und Kristalloiden. - Gut erhalten. - DSB 5, 492; Darmstaedter S. 609.
