The Effect of Electrolytes on the Cataphoretic Mobility of Colloidal Carbon.

Abstract

Although the colloidal properties of a large number of sols have been studied, very little is known about the nature of colloidal carbon. Carbon is used in many industries, especially in the manufacture of ink. Chinese ink, for example, is essentially a colloidal dispersion of carbon, with gelatin as the protective agent. Some knowledge of the colloidal properties of carbon is therefore of practical importance. In this laboratory we plan a
