Ultrafiltration In The Pigment Field : A Critical Literature Survey, Charles Walter Manger
Theses
The objective in this work has been to determine, through a critical literature survey, the possible application of ultrafiltration, and other related techniques, towards the solution of certain problems encountered in the research and testing of various pigments.
Among these problems may be mentioned the following:
- The determination of water-soluble salts in pigments, which when dispersed in water to leach out the salts, tend to peptize, thus being unfilterable through the usual filter paper. Among these pigments are the following: iron blue, certain chrome yellows, pigment green B, copper maroon, and several others. It may be added that these pigments …
