A polarographic study : the estimation of sodium and potassium in the presence of each otherCarter, Austin John January 1938 (has links)
The polarographic method has been described, and an attempt made to describe the difficulty of the simultaneous deposition of sodium and potassium. Various methods have been examined, of which precipitation of potassium with magnesium dipicrylaminate seems the most promising. The quantitative results were unsatisfactory, and possible sources of error are discussed. The method, while very convenient, rapid and labour-saving, is not sufficiently standardised to be trustworthy.

The polarographic determination of trace elements in blister and refined copperEve, Adrian John January 1954 (has links)
In the complete analysis of copper the following impurities are generally determined: silver, gold, lead, arsenic, antimony, selenium, tellurium, iron, zinc, cobalt, nickel, oxygen, sulphur, and, less commonly, tin and phosphorus. The actual copper content varies around 99.0% in blister copper; in the refined metal the content is somewhat higher, usually over 99.9%. The concentrations of the individual impurities vary from tenths to thousandths of one per cent.

A study of the polarographic reduction of some organic nitro compounds in anhydrous acetic acidRisk, James Berryman January 1956 (has links)
Polarographic results for the reduction of a number of aromatic compounds in anhydrous acetic acid were obtained. The compounds studied included: o-, m- and p-nitroanilines and nitro-phenols; o-nitrobenzoic acid; 2,4-dinitro substituted phenol, benzoic acid and toluene; 3,5-dinitro substituted phenol and benzoic acid; 2,4,6-trinitro substituted phenol, benzoic acid and toluene.
It has been shown that activating substituents on the benzene nucleus hinder the reduction of nitro groups on the ring, the effect being most pronounced for the o- and p- positions. Hydrogen bonding has been shown to occur to a lesser extent in acetic acid than in aqueous solution. Deactivating groups have been shown to cause nitro substituents to be more easily reduced, the effect decreasing in the order o<m<p.
The polarographic reduction of a nitro group has been postulated to proceed with the same mechanism as in aqueous solvents.
This reduction has been assumed to be a four or six electron irreversible reaction to the hydroxylamino or amino group repectively.
Acetic acid, although limited in the potential range available, has been determined to be a suitable solvent for polarographic studies of organic compounds. / Science, Faculty of / Chemistry, Department of / Graduate
