A Study Of The Adsorption Of Some Atmospheric Gases On Soils Of The Willamette Valley River Basin, Thomas R. Quale

Dissertations and Theses

Recent work indicates that microorganisms present in soils can remove carbon monoxide from the atmosphere and as such constitutes a major sink. B.E.T. adsorption studies were carried out on representative soils from the Willamette Valley River Basin in order to determine their adsorptive characteristics for carbon monoxide and other gases. Attempts were made to isolate, through a non-soildestructive sterilization, the adsorptive characteristics of the soil microorganisms as well as of the test soil.

The carbon monoxide studies show physical adsorption equivalent to the coverage of a few per cent of the surface area at 25.0° and 76 cm-Hg. Adsorption studies …

Synthesis Of Uranium Fluorosulfates And The Group Vi B Difluorophosphates, Larry Mccain Emme

Dissertations and Theses

Some reactions leading to several anhydrous Uranium fluorosulfates through the use of fluorosulfonic acid or peroxydisulfuryl di-fluoride have been studied. It was found that HS0F can oxidize uranium 3metal to the +4 state or the +2 state depending on the reaction conditions. The synthesis of the tan solid; U(S0₃F)₄ and the pale green solid thought to be U(S0₃F)₂ were prepared in this manner. It was found that S₂0₆F₂ can also oxidize uranium to yield the green solid U(S0₃F)₃. S₂0₆F₂ was …
