| Abstract: | A long path atomic absorption cell has been modified to achieve high sensitvity in the determination of lead after MIBK extraction. This was achieved by using thermal insulation of the absorption cell and positioning the burner at an optimum angle. Insertion of rings inside the cell and oxygen supply line reduced the background noise to a low level while producing high sensitivities. This resulted in a marked improvement in detection limits for some metals in aqueous solution. |
