Synopsis
Excerpt from Properties of the Colloidal Soil-Material
The colloidal materials from seven soils were examined by the method of Siedentopf and Zsigmondy. The suspensions directly from the centrifuge were diluted with optically pure water in such proportions that in the final dilution an average of one to three particles were visible in the field at one time. The blank count of the water averaged 0. 035 of a particle. In order to promote dispersion and to prevent as far as possible the aggregation of primary parti cles, ammonia was added ln each case to1 n/2oo. The particles were observed with an ultramicroscope of the Siedentopf -zsigmondy type, which was provided by the microchemical division, Bureau of Chemistry.

Paperback. Etat : New. Print on Demand. This book uses an in-depth chemical analysis to compare seven distinct colloidal soil materials with three more â" silica gel, bentonite, and gelatin. With the use of ultramicroscopic determination the author was able to provide particle size, specific gravity, and heat of wetting for each. This detailed study of these materials provides a better understanding of soil composition and character. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
