B DETERMINATION OF ALUMINIUM BY ICP-OES

1 Solutions with aluminium compounds are nebulised into an argon plasma, where 

2 This determination may be carried out on digest 2.3 (miaowave digestion with 

digest 2.4 (digestion with HNO3 - Hp - HF) and digest 2.7 (digestion by dry-ashing followed by treatment with FIF). 

1 This procedure yields a standard curve that is linear up to at least 100 mg/L Al. 

2 The detection limit is approximately 0.035 mg/L in the digest. The determination limit is approximately 0.10 mg/L (12 respectively 33 mg/kg Al in the dried plant material).
