Note on Polarographic Determination of +6 Uranium

A polarographic method is proposed for determination of small amounts of +6 uranium. An aqueous solution of salicylic acid (1.6 g /l), sulphuric acid (0.4% v/ v) and thymol (0.009 %) is used as supporting electrolyte. This procedure is applicable in the concentration range from 5 to 50 μg of uranium per ml. of the solution used for polarographic measurement. Total amounts of 10 μg of uranium per sample can be determined with a standard error of ± 0.8 μg

The Solubility of Silver Bromide in Aqueous Solutions of Potassium Bromide and Silver Nitrate at 20 °C

The solubility of silver bromide at 20° C in aqueous solutions of potassium bromide and silver nitrate has been measured over a concentration range from 2.5 X10-7 M to 3.5 M for KBr and from 0.115 to 4.05 M for AgNO3. A turbidimetric and an absorptiometric method were used. The influence of ionic strength on the complex solubility of silver bromide is briefly discussed

The Complex Solubility and the Composition oi Aqueous Complex Solutions of Silver Halides and Silver Thiocyanate

The numerous data on complex solubility of silver halides and silver thiocyanate in aqueous solutions have been systematized and the solubility curves constructed. The data are discussed in relation to the experimental techniques used, to the effect of the ionic strength, and to the influence of the accompanying cations from halide component. The comparison of the solubility curves for various silver halides and silver thiocyanate has been made

Polarographic Behaviour of +6 Uranium in a Mixture of Salycilic and Sulphuric Acid

The half- wave potential, the diffusion coefficient and the diffusion current constant of + 6 uranium in the supporting electrolyte containing 1.60 g/l salicylic acid, 0.4% v v sulphuric acid and 0.009 % thymol (as maximum suppressor) have been determined. The electrocapillary curve of mercury in this electrolyte is also given
