摘要：

Poly(vinylbenzyltetraaza-1,4,8,11-cyclotetradecane) was synthesized and used for the preconcentration of manganese from sea water prior to its determination by graphite furnace atomic absorption spectrometry. The improvement in the porosity of this new polymer has a significant effect on the rates of the extraction and back-extraction steps in comparison with previously described polymers. Swelling, capacity and pH effects were studied by the batch technique. The validity of the method is demonstrated by comparison with the quinolin-8-ol-chloroform liquid-liquid extraction system. The blank of the method is ca. 0.15 nmol 1-1 and the relative standard deviation for duplicate analyses of coastal sea water is 8%. © 1990.
