Effect of Autoclaving on X-Ray Characteristics of Clay Minerals1
- G. Stotzky and
- L. E. DeMumbrum
A variety of tropical and temperate zone soils differing in clay mineral composition and moisture content were autoclaved for 1 hour at 121 C, 15 psi, and fast exhaust. Various purified clay minerals were similarly autoclaved for 15 min in a nutrient medium used for the culture of microorganisms. Autoclaving did not significantly alter the diagnostic d values of the clay minerals contained in either the soils or the nutrient medium, regardless of the moisture content (from oven-dry to saturation) of the soils at the time of autoclaving.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
