On the Volumetric Determination of Titanic Acid and Iron in Ores.

Abstract

HE difficulties connected with the gravimetric determina-T tion of titanic acid tnake R reliable volumetric method very desirable, especially for the analysis of titanic iron ores. W e have therefore turned our attention to this subject and have found that satisfactory results can be obtained b y a slight modification of a process which has long been known.

Reduction Method for Evaluation of Titanium Dioxide

“…A review of the literature relating to the evaluation of titanium by reduction and subsequent titration with an oxidizing agent indicates that, although there are a number of volumetric methods for determining titanium, certain objections have been raised in accepting these methods for industrial routine analysis. The methods of Pisani (8), Marignac (-5), and Wells and Mitchell (10) either give low results or require operating in an atmosphere of carbon dioxide. The procedure described by Newton (7) gives good results, but it is necessary to work in an atmosphere of hydrogen, employing a flask, delivery tube, and separatory funnel.…”
