摘要：
Batch and flow-injection determination of magnesium in blood serum, based on the adsorptive reduction current peak of the Eriochrome Black T-magnesium complex, is described. A potential-scanning electrochemical detector, equipped with a novel thin-film deaerator, allows the successful adaptation of the batch method to a flow-injection system. Using a simple flow system, up to 35 samples h-1 can be processed. The results obtained agree well with those obtained by atomic absorption spectrometry. © 1990.
