| Abstract: |
| In the present paper, the content of magnesia in 5 XXX series aluminum alloy was determined by inductively coupled plasma atomic emission spectrometry (ICP-AES) . The sample was digested by 20 mL dilute aqua regia medium to overcome the interference of matrix elements and other coexisting elements in the alloy then the content of magnesium was measured by ICP-AES at 280.270 nm as analytical spectral line . Three kinds of aluminum alloy standard materials, as well as the sample (with the similar matrix) were weighed to 0.100 0g for digestion, then the digestion solutions was kept at 100 mL. Instruments operating parameters were studied and calibration curves were made. The above-mentioned four samples were determined six times, respectively. The relative standard deviations (RSDs) were less than 0.59%.The recovery was in the range of 94.0%~104.0%. The measured values of magnesia obtained by the proposed method in 5 XXX series aluminum alloy were consistent with those obtained by 1, 2-diaminocyclohexane tetraacetic acid separation and complexmetric titration method. |
