Abstract
Aluminum (III) ,and chromium (III) were chelated with trifluoroacetylacetonate (TFA),
determined by gas liquid chromatography (GLC) with electron capture detector (ECD), while iron (III)
was treated similarly ; but their chromatography suffered from number of practical difficulties . The
technique was reliable for aluminum; although very sensitive was quite time consuming. Selenium was
converted to the 4-chloropiazselenol and extracted into toluene for analysis. The Se (VI) was first
reduced to Se (IV) by adding HCl and HBr with heating for more than 2 hours at 100 Cº. Estimation of
selenium by gas liquid chromatography with ECD considers very sensitive technique allowing
pictogram (10¯¹²gm) amount of selenium can be determined. The analysis of the sample (Drinking
water at Tikreet city) was shown that the level of Al, Cr, Fe, Se in water below the detection limit of
GLC with ECD.
