An Investigation Of Phosphate Adsorption By The Clays Montmorillonite And Kaolinite /|Cby Gordon Richard Bradford, G. R. Bradford

Theses and Dissertations

Clay minerals have widespread application in industry and play an important role in plant life (2, 17). It is the adsorptive capacity of clay which determines largely its importance to man (2). The purpose of this investigation is to interpret the mechanism of adsorption of the phosphate anion by the two clay minerals montmorillonite and kaolinite. This particular system was singled out for two reasons: 1. It has agricultural significance. 2. It is believed that if the particular phosphate adsorption mechanism is understood it will aid in an understanding of many other adsorption phenomena associated with clay.

A Study Of Fossil Resins In Huntington Canyon Coal, Ross D. Gardner

Theses and Dissertations

The object of this investigation was to determine whether or not a certain sample of raw resin, collected by Mr. Adriaan Nagelvoort from coal from Huntington Canyon, Emery County, Utah, could be separated into more than one fraction with each fraction having distinctly different properties. Three methods of separation were attempted: (l) Separation of specific gravity fractions, (2) separation by use of solvents, and (3) chromatographic separation. Properties determined as a means of establishing any differences in the resins were: solubility, softening points, acid numbers, and iodine numbers.

Physical Properties Of Ellis County Adobe, William G. Read

Master's Theses

Houses made of soil have been built for centuries, but until recently the trend had been away from soil to some other building material. Now, however, adobe is again beginning to be recognized as a satisfactory, reliable building material for our time. Recently, especially in the southwestern part of the United States, a surprising number of dwellers have turned again to earth for their building material. They are following in the footsteps of the early settlers, who constructed many missions and other buildings from sun-dried earth. Many of these buildings, although aged, are still in use or may be viewed …

Concentration Of Manganese Dioxide From Philipsburg, Montana, W. M. Mcauliffe

Bachelors Theses and Reports, 1928 - 1970

Imports of manganese ore probably supply a major proportion of the needs of the United States. Domestic production is reported to be higher than pre-war levels, but does not equal that of the peak production year of 1943. In 1946, the Anaconda Copper Mining Company ac­counted for 90 percent of the total shipments of mangan­ese nodules, and this company is the largest producer of domestic metallurgical ore in the United States.

Solubility And Physiological Availability Of Phosphates In Sodium And Calcium Systems, Parker F. Pratt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One of the principal fertility problems of calcareous soils is the lack of available phosphates. The factors which control this availability are not completely understood. One hindrance to the solution of the problems involved results from confusion of the concepts of solubility and availability. Availability is the net effect of the chemical state of a plant nutrient element and the ability of the plant to utilize the forms of the element present under the existing chemical and physical environmental conditions. In this paper, the term solubility will be used to designate the chemical solubility of an element in water or …

Sandstones Of The Lance And Fort Union Formations, Alan G. Conner

Bachelors Theses and Reports, 1928 - 1970

Bachelors Theses and Reports, 1928 - 1970

This investigation concerns the development of a satis­factory method or extracting or concentrating gold and silver from the ores of the U. S. Grant Mine. The choice between applying an extractive process and one by which the valuable mineral constituents are concentrated depends on more than one factor.

Conductance Of Organic Nitrogen Compounds At Their Melting Points, Leonard Joseph Burant

Bachelors’ Theses

Even though there are many practical applications using the conductance of fused salts, such as the commercial preparation of aluminum, sodium, potassium, calcium, and magnesium, there is very little in the literature on such conductance.

Because organic compounds as a class do not conduct as well as acids, bases, and salts, even less attention has been paid to the conductance of organic compounds in the fused state. Since the author has had some experience with organic preparations, it seemed worth while to prepare certain types of related heterocyclic organic compounds and to test their conductance in the fused state.

The Identification Of Alkyl Halides Through Conversion To Alkyl 3, 5 Dinitrobenzoates By A Reaction Between The Alkyl Halide And A Metallic Salt Of The Acid, James L. Finnerty

Bachelors’ Theses

To materially aid in the identification of a series of organic compounds one must develop a new system of derivatives or suggest better methods for preparing known derivatives. The problem of characterizing alkyl halides is one in which there is room for improvement, for the best derivatives of these compounds are now prepared by means of the Grignard reaction which may often fail to give satisfactory results. Moreover, there is a series of solid alkyl esters, the 3, 5 dinitrobenzoates, which serve very well for the identification of aliphatic alcohols, and which should be applied to the alkyl halides if …

The Effect Of Light, Soil Temperature, And Soil Moisture On High-Lime Chlorosis, Lauren M. Burtch

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Chlorosis of plants from a lack of available iron is one of the most common plant nutrient problems of the calcareous soils of the west. The disease is characterized by a yellowing of the plant leaves and is accompanied, in severe cases, by a partial root death and premature defoliation (3). In addition to reducing growth, the disease greatly reduces the quality and yield of plants.

Many types of plants are affected by iron chlorosis. In Hawaii and Porto Rico rice, sugar cane and pineapple are susceptible, while in California and Arizona, citrus trees are seriously affected. In Utah apples, …

A Discussion Of The Geology And An Isopach Map Of The Pennsylvanian System In Wyoming And Adjacent Areas, B. R. Alto

Bachelors Theses and Reports, 1928 - 1970

Pennsylvanian strata in Wyoming and adjacent areas have been the subject of much work and discussion. Most of the work has been due to the economic importance of the system as an oil producer in this region. Oil production from strata of Pennsylvanian age is rather recent history; and therefore, much of the available information is local­ized and incomplete.

An Isopach Map And A Discussion Of The Permian In Wyoming And Adjacent Areas, Willard Leskela

Bachelors Theses and Reports, 1928 - 1970

The accelerated post-war demand for petroleum products with resultant high prices and dwindling reserves has spurred producers to an extensive search for new fields and for ad­ditional production in known fields. Exploration and discov­ery is dependent on the collection and correlation of vast amounts of data both in the field and that found in liter­ature.

Sulfatizing Roasting Of A Copper Sulfide Ore, Walter D. Finnegan

Bachelors Theses and Reports, 1928 - 1970

At present copper sulfide ores are recovered by pyrometallurgical processes. While the recovery of cop­per from sulfide ores by hydrometallurgical means has long been considered attractive, the impurities, low re­covery and mechanical difficulties have kept this process from becoming commercial.

Roasting And Leaching Of Montana Chromite, Jerry D. Murphy

Bachelors Theses and Reports, 1928 - 1970

The United States, although the leading consumer of chromite, depends almost entirely on imports for its supply. Domestic production of chromite is limited, because high-grade imported ore is plentiful and inexpensive in normal times. There are several large deposits of chromite in the United States, representing millions of tons of low grade ore. These deposits form a strategic reserve that must be used in time of national emergency.
