The titrimetric determination of alumina in ceramic materials by using DCTA in place of EDTA

Abstract

The replacement of EDTA by DCTA (1,2-diaminocyclohexanetetraacetic acid) has a number of advantages. The reagent can be applied to the analysis of the silica-alumina range of materials and appears to be applicable to magnesites and chrome-bearing materials. The use of the reagent saves the time spent in boiling and cooling the solution so as to ensure that the alumina is fully complexed. As chromium does not react in the cold and aluminium does, the analysis of magnesites, dolomites and chrome-bearing materials would also be simplified. The method is described in detail.
