Solubility Of Manganese And Iron In Impoundment Waters, Jim Gilbert

Honors Theses

The purpose of this paper is to show the rate of solubility of certain elements (manganese and iron) in impoundment waters. The rate at which manganese and iron becomes soluble is important in determining if there is a change in the solubility of these elements in impoundment water and free running water.

The solubility of an element under impoundment waters represents a cycle. The mud on the bottom of impoundment waters contain the elements that are insoluble. At a certain stage the element becomes soluble, and it is released from the mud. The soluble element is much lighter than the …

(Ultra-Rapid) Fluorescent Labelling Of Proteins, Cynthia Elaine Wilson

Honors Theses

The goal at the outset of this research project was to prepare fluorescent labeled bovine plasma albumin. A reprint of "Ultra-Rapid Fluorescent Labelling of Proteins" by Dr. Henry Rinderknecht, Director of California Corporation for Biochemical Research, Los Angeles, California, was secured to serve as reference material for the project.

Kinetics Of The Decomposition Of The Cupric Ion Sulfhydryl Bond In Beef Plasma Albumin, Gary Rice

Honors Theses

The purpose of this work was to study the kinetics of the binding of cupric ion to beef plasma albumin, in particular the decomposition of the Cu++--BPA complex which absorbs light at 375 millimicrons.

The work of Klotz, Urquhart, Klotz, and Ayers has shown that the characteristic absorption band at 375 mu produced by the binding of cupric ion to beef plasma albumin is due to a copper- sulfhydryl bond. They have further demonstrated that the disappearance of this absorption band with time is accompanied by irreversible changes in the structure of the protein. The intensity of the initial absorption …

Ionium Age Determination, Leon Johnson

Honors Theses

Natural radioactive decay provides a means of determining the age of geological specimens. It is found that the number of atoms of a radioactive isotope disintegrating per unit time is linearly proportional to the existing number of atoms and independent of exterior parameters.

An Attempt To Determine Molybdenum By Atomic Absorption Spectrophotometry, Gary Rice

Honors Theses

An attempt was made to work out a method for routinely determining molybdenum by atomic absorption spectrophotometry. A stock standard was prepared containing 100 ppm molybdenum as MO4. Sensitivity of the spectrophotometer was found to be zero for aqueous solutions in the 1-10 ppm range. A pH-dependence study of extraction of the molybdate with DDC and MIBK gave best results at about pH 4.
