Chronopotentiometry of Sm(II) and Pm(III) in molten LiCl-KCl eutectic

Creator:: Nixon, Richard Allen
Abstract:: Samarium (III) and promethium (III) were studied by chronopotentiometry in a molten LiCl-KC1 eutectic. Tungsten electrodes were used to avoid alloying effects encountered with platinum electrodes. Adsorption phenomena were observed which prevented the study of any kinetic effects. The quarter wave potentials were measured as: Sm(III) = 0.95 ± 0.05...

The analytical application of the galvanic dissolution of niobium and tantalum : the determination of nitrogen

Creator:: VanSanten, Richard Theodore
Abstract:: Nitrogen is a contaminant of niobium and tantalum adversely affecting the workability of the metal. With recent interest in the refractory metals, one problem the chemical analyst must solve is the accurate determination of nitrogen in niobium and tantalum at very low levels. The usual method of assaying for nitrogen...

Determination of magnesium in zirconium based on ion exchange separation and titration with versene

Creator:: Metzler, Richard Kenneth
Abstract:: The Kroll Process for the production of zirconium utilizes the reduction of zirconium tetrachloride with metallic magnesium. Control of the magnesium content of the final zirconium metal is essential, as residual magnesium adversely influences the properties of zirconium. In this thesis a volumetric method has been presented for the determination...

The design and evaluation of a recording conductometric titrator

Creator:: Knarr, Richard Dennis
Abstract:: A Heath EUW-20A Servo-Recorder was converted to a self-balancing, recording Wheatstone bridge. The EUW-20A 10000Ω slide-wire was used as the variable resistance arm of the bridge, the servo-amplifier was used as the bridge unbalance signal detector, and the servo-motor was used to balance the bridge automatically. The bridge was arranged...

Flame ionization detection of hydrocyanic acid ; Analysis of trace aqueous solutions

Creator:: Claeys, Robert Raymond
Abstract:: A gas chromatographic procedure was developed for the determination of nanogram quantities of hydrocyanic acid using a flame ionization detector. Excellent chromatograms were obtained on a porous polyaromatic polymer column (Porapak Q) at 60°C. The procedure was employed for the analysis of HCN in aqueous cyanide solutions. Solutions as low...

Gas chromatography of metal halides

Creator:: Dennison, James Eugene
Abstract:: An all-glass gas chromatograph was developed for the analysis of corrosive metal halides. Included in the apparatus is a new liquid sampling system designed for fast repetitive sampling of corrosive liquids in an inert atmosphere. A flame photometer detector was developed to permit the detection of corrosive solutes in the...

Optimization of the continuous analysis Pearl-Benson method for lignosulfonates

Creator:: Blaine, Roger Lee
Abstract:: A procedure is described for the optimization of a previously described continuous analysis adaptation of the Pearl-Benson or nitroso method for estimation of spent sulfite liquor (SSL) or ligno-sulfonates. The optimized procedure has a response time of 6.5 minutes. In order to monitor samples whose SSL concentration is between 0...
