Abstract

A flow-cell colorimetric technique has been developed by which Al concentrations of 0.0003to 0.1 wt. percent can be analyzed in one-microliter fluid samples.An A1-complexing reagent (Ferron) continuously flowing through teflon capillary tubing is spiked with one-microliter aliquots of solutions containing A1. The sample reacts with the reagent and subsequently passes through a microcolorimeter. Measurement of less than one nanomole A1 is possible by comparing the integrated absorbance of unknown samples with standard solutions.
