Flow injection flame atomic spectrometric determination of aluminium, iron, calcium, magnesium, sodium and potassium in ceramic material by on-line dilution in a stirred chamber

Abstract

The on-line dilution of ceramic samples, previously fused with alkaline carbonates, increases the dynamic range of the flame atomic spectrometric determination of aluminium, iron, calcium, magnesium, sodium and potassium. A double-channel manifold with a simultaneous double injector, and a versatile system of dilution, with stirred chambers, allows direct determination of the six elements studied in different ceramic matrices, i.e., clay, kaolin, quartz, felspar, varnish, stoneware and porcelain, rapidly and with low consumption of the reagents. The effect of the flow injection parameters on the analytical characteristics of the flame atomic spectrometric determination has been studied and the results obtained in the analysis of real samples have been compared with those found in batch analyses.
