The Separation and Concentration of Titanium(IV)

2019-12-12  This paper presents research on separating and concentrating titanium(IV) from aqueous sulfuric acid solution, using trioctylamine (TOA) as extractant and kerosene as a diluent. We investigated the effects of reaction time, temperature, sulfuric acid concentration, organic/aqueous phase ratio, TOA concentration, and titanium concentration on the removal efficiency of titanium(IV).

4.2 Results—Titanium Concentration of Deformed Quartz. Results from quantitative analysis reveal three distinct populations of [Ti] in quartz, each of which correlates with a particular microstructural domain in recrystallized quartz (Table 1 and Figure 6). The cores of elongate quartz ribbons preserve the highest Ti concentrations in all quartzite mylonite samples.
