Determination of active oxygen in the presence of barium and lead
M. Fleischer
1943, Industrial and Engineering Chemistry (15) 31-32
The method of Mrgudich and Clark is modified by substituting 5 per cent (by volume) perchloric acid for 50 per cent perchloric acid. Titration by potassium permanganate may be substituted for electrometric titration with ceric sulfate....
Determination of small amounts of molybdenum in tungsten and molybdenum ores
F. S. Grimaldi, R. C. Wells
1943, Industrial and Engineering Chemistry (15) 315-316
A rapid method has been developed for the determination of small amounts of molybdenum in tungsten and molybdenum ores. After removing iron and other major constituents the molybdenum thiocyanate color is developed in water-acetone solutions, using ammonium citrate to eliminate the interference of tungsten. Comparison is made by titrating a...
Report of the International Board of Inquiry for the Great Lakes Fisheries
Hubert R. Gallagher, A.G. Huntsman, D. J. Taylor, John Van Oosten
1943, Report, International Board of Inquiry for the Great Lakes Fisheries, Report and Supplement
This is the report of the International Board of Inquiry relative to the preservation and development of the Great Lakes fisheries as provided by an exchange of notes between Canada and the United States on February 29, 1940. The report aims to present in a very brief manner the...
Supplemental report of the United States members of the International Board of Inquiry for the Great Lakes fisheries
Hubert R. Gallagher, John Van Oosten
1943, Report, International Board of Inquiry for the Great Lakes Fisheries, Report and Supplement
This is a supplement to the report of the International Board of Inquiry relative to the preservation and development of the Great Lakes fisheries as provided by an exchange of notes between Canada and the United States on February 29, 1940. The report aimed to present in a very...
Determination of iron in the presence of chromium and titanium with the Jones reductor
F. S. Grimaldi, R.E. Stevens, M. K. Carron
1943, Industrial and Engineering Chemistry (15) 387-388
Sulfuric acid solutions of titanous and chromous sulfates, obtained by passage through the Jones reductor, are oxidized by aeration for from 5 to 10 minutes in the presence of a trace of copper sulfate as a catalyst. Ferrous sulfate is essentially unoxidized and is titrated with permanganate after aeration. Best...
The Arlington copper mine: North Arlington, New Jersey
Henry Rowland Cornwall
1943, Report
The Arlington copper mine is located in North Arlington, Bergen Co., N. J. The ore deposit occurs in a 10- to 30-foot thick arkosic sandstone layer, interbedded in red shale. Copper mineralization is associated with thin diabase sills and dikes. It would probably not be feasible to develop the underground...
Underground-water investigation in Utah: A part of Chapter 5 in Twenty-third biennial report of the State Engineer to the governor of Utah: 1940-1942
P.E. Dennis
1942, Utah State Engineer Biennial Report 23-5
Systematic underground-water investigations have been in progress in the State of Utah since 1935 by the Federal Geological Survey in cooperation with the state engineer. The general plan and outline of these investigations, together with a summary of results accomplished to June 30, 1940, are given in the Twentieth, Twenty-first,...
The anaesthesia of fish by high carbon-dioxide concentrations
1942, Transactions of the American Fisheries Society (72) 25-29
A practical and economical method for anaesthetizing adult salmon and steelhead trout in the fish trucks used in the Grand Coulee fish salvage program is described. The method consists in generating a predetermined carbon-dioxide concentration in the 1000-gallon tanks of the trucks through the successive addition of predissolved sodium bicarbonate...
