| 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. | ||
