Electroanalysis and Coulometric Analysis

Abstract

review mainly surveys the literature during 1960 and 1961, and is patterned closely after previous reviews in this series. Papers published before 1960 which have not appeared in previous reviews have also been included. Research has increasingly been concerned with a study of the funda-

Continuous Coulometric Titration of Unsymmetrical Dimethylhydrazine.

“…The current response, 7, for an incoming sample completely titrated at a rate of n electrons per mole per second is given by A/ = /total -Tase line = yFCP/RT (1) where n is the number of electrons transferred per mole of sample, e.g., equivalents per mole, Fy is the Faraday O INNER (REACTION) CELL Q RESERVOIR (pressure) and P is the total pressure in atmospheres, R is the gas constant 82.06 cc. atmospheres per mole degree Kelvin, and T is degrees Kelvin.…”

“…As yet no formulation of this relationship has been undertaken. Keulemans ( 1 ) has constructed a n analogue device that permits the contamination of one Gaussian peak with another of any size having any desired mobility. I t has been used to predict the separation a t which two maxima will be visible and some trial computations of the displacement of a given peak by a known contaminant have been carried out.…”

Electrochemical Preparation of Thin Metal Films as Standards on Pyrolytic Graphite

“…The electrode surface was pretreated by polishing with No. 600 carborundum paper followed by No. 1 Whatman filter paper.…”

Nucleonics

“…DeVoe and Meinke (372) and Parker and Grunditz (1255) describe distillation and volatilization procedures and the apparatus used in the rapid carrier-free separations of radioactive nuclides not isotopic with the target material. Electroanalysis methods to separate radioactive nuclides have been reported (101,195,206,991,1546).…”
