本文报道了α-已基吡啶在萃取微量金中的应用。研究了萃取酸度、溶剂、萃取剂浓度、反萃取及共存离子等对萃取的影响。拟定了萃取火焰原子吸收测定微量金的方法。本法适用于矿石及选矿尾矿中0.01—1克/吨金的测定。
This paper reports the application of α-hexylpyridine in the extraction of trace gold. The effects of extraction acidity, solvent, extractant concentration, stripping and coexisting ions on the extraction were studied. A method for the determination of trace gold by flame atomic absorption spectrometry was developed. This Law applies to the determination of ore and ore tailing 0.01-1 g / tonne gold.
