摘要：

The application of multicomponent techniques in sequential injection analysis is considered. Such a scarcely selective chromogenic reagent as 4-(2-pyridylazo) resorcinol allowed the simultaneous spectrophotometric determination of Ca and Mg in environmental samples. The process was carried out in a fully automated fashion by using a personal microcomputer running software for instrumental control and data acquisition and processing. The ensuing method features a linear determination range of 1-20 and 2-40 mg l(-1) for magnesium and calcium, respectively, and a sample throughput of 60 h(-1) The results are compared with those provided by batch and flow injection methodology.
