Abstract
Micro-determination of metals by flame photometric method was studied in which metals were changed into their oxine complex and the extracted complex with organic solvent was excited in the oxygen-hydrogen flame and measurements of the intensities of titanium, gallium and indium were made by using respectively the band head at 518mμ, the line at 417.2mμ and the line at 451.1mμ.
The for conditions determination were examined in each case using the following solvents, methyl isobutyl ketone, amyl acetate, ethyl acetate and chloroform, and it was confirmed that the sensitivity could be increased 515 time than in the case of aqueous solution by selecting optimum gaseous pressure for each solvent.
