✦ Synopsis

There are a number of difficulties peculiar to the analysis of steel which have to be faced in developing any method of analysing this metal. For instance, the large quantities of iron present have usually to be separated from the impurities which arc being analysed. These difficulties are manifested in physical methods by the necessity of a large spectrograph in spectrographic analysis and the difficulty in eliminating the iron step in polarographic analysis. In wet methods the separation of the iron is often difficult and this is particularly so in the estimation of aluminium in steel where the properties of the elements being separated arc very similar. The principal methods used for this have included the mercury cathode separation, organic solvent extraction processes etc., but the procedures have proved either lengthy or incomplete. Among the extraction processes we find ether, dichlorodiethyl ether, amyl acetate' and ether with a tetrahydro furan a. In the present work, attention was paid to the use of dichlorodiethyL ether (dichloroether) and amyl acetate.
