Abstract
Methods for the simultaneous determination of aluminium and manganese, aluminium and iron(III), and calcium and magnesium, based on the use of dual spectrophotometric detection in segmented now analysis, were d eveloped. Ligand-exchange reactions or reactions at different rates we re used. The methods were tested on both synthetic and real samples (s oil extracts, sedimentary rock). Up to 32 samples per hour can be anal yzed. A rapid flow analyzer with double-beam spectrophotometer was use d for the analyses. Relative standard deviations were 1.0-6.5%.
