摘要
报道了在１０％王水介质中，有Ｂｒ２存在时用二苯基硫脲—甲基异丁酮泡沫塑料富集、Ｘ射线荧光测定痕量金的分析方法。
Method for measuring trace gold with X-ray fluorescence after pre-enrichment is presented. The gold is enriched in a medium of 10% aqua regia in presence of Br 2 with polyurethane foam loaded with diphenylthiourea and methyl isobutyl ketone.
