泡沫塑料富集原子吸收光谱法测定金矿中的金
摘要：试料经高温焙烧后,用王水（50%）在电热板上加热溶解,在王水溶液的体积分数φ（王水）为10～15%和少量三氯化铁溶液的介质中,用聚氨酯泡沫塑料吸附富集金,再用硫脲—盐酸（10g/L）溶液解脱,根据其含量,所得溶液用火焰原子吸收光谱法.优化了样品处理、泡塑富集、解吸条件,以及火焰原子吸收光谱法测量条件.火焰原子吸收光谱法测量金的检出限为0.574ug/mL,相对标准偏差RSD为6.5%,方法应用到实际样品的检测,

Foam enriched atomic absorption spectrometry determination of gold in gold ore
Abstract: The sample after calcination, with aqua regia (50%) was dissolved by heating on a hot plate, the volume fraction of the aqueous solution φ (aqua regia) is 10 to 15%, and a samll amount of ferric chloride solution as medium, and using enriched polyurethane foam to absorb gold, then thiourea - hydrochloric acid (10g / L) was to dissolve, according to its content, the resulting solution was determined by the flame atomic absorption spectroscopy. To optimize sample handling, foam enrichment, desorption conditions, the flame atomic absorption spectrometry measurement would gain the best results. Flame atomic absorption spectrometry measurements of gold detection limit of 0.574ug/mL, and the relative standard deviation (RSD) was 6.5%, the method is applied to detect the actual samples with satisfactory results.
