摘    要：

用泡沫塑料搭载三正辛胺富集分离矿石地质试样中低含量的金，经硫脲洗脱处理后，以火焰原子吸收光度法测定．对富集时间、硫脲浓度、解析时间、王水浓渡等因素进行试验，最终确定了最佳试验条件，该方法的准确度和精密度都达到要求．

Abstract:

Foam with Toa enrichment ore geology of the low content of the sample, with thiourea-eluting after processing, in order to flame atomic absorption spectrophotometry. To enrichment time, parsing time concentration,thiourea, aqua regia and factors such as concentrated to the ultimate test to determin the optimal test conditions,the accuracy and precision of the method is to meet the requirement.
