泡沫塑料快速富集－石墨炉原子吸收法测定化探样品中的痕量金

DETERMINATION OF TRACE GOLD IN ORES BY RAPID PRECONCENTRATION WITH POLYURE THANE-FOAM AND GRAPHIC FURNACE ATOMIC ABSORPTION SPECTROMETRY

本文系统研究了泡沫塑料快速富集－石墨炉原子吸收法测定金的方法，对泡沫塑料富集、分离金和石墨炉原子吸收法测定金的条件均做了详细的研究。该法用于化探样品中金的测定，结果与推荐值相符。

Determination of trace gold in ores by rapid preconcentration with polyurethanefoam and furnace atomic absorption spectrophotometry was studied systematically in this paper. The conditions for separating and preconcentrating gold by polyurethane-foam and the determination of gold were studied in detail. The results are satisfactory.
