摘要：
A method for determining the aluminium levels in local water, tea leaf digest, tea and coffee infusions by means of on-line cation exchange flow-injection-flame atomic absorption spectrometry (FIA-FAAS) is described. Quantitative results can be carried out down to 75 ng ml-1 of Al using sample volumes in the range 6.0-24.0 ml. The method using a conventional FAAS system was found to be rapid, simple and relatively inexpensive offering good selectivity and typical R.S.D.s of 1-2% (n = 10) with a relative error of about 2%.
