The Coulometric Determination of Carbon in Steel,

摘要

A method suitable for referee analysis has been developed for the precise determination of carbon in steel. It employs coulometric titration of carbon dioxide absorbed in an almost non aqueous medium. The apparatus is inexpensive and the procedure is simple. Suggestions are made for automating the technique to provide a rapid routine method of high precision. The analytical performance of the recommended method compares well with that of low pressure volumetric methods. Standard deviations of 0.00035% at the 0.05%C level to 0.004% at the 1% carbon level have been obtained.
