近年来,出现了用蛋白质富集金的手段.武者宗一郎等用豆腐脑富集水中金,kamel等用电泳法分高血液和乳浆中的含金蛋白凝胶.但是,他们的试验只限于在微酸性溶液中进行;这种富集法还未见用于矿石分析中.我们用动物蛋白质(鸡蛋、鸭蛋或鹅蛋均可)对富集金的可能性作了试验.确立了在王水或盐酸—过氧化氢溶液中的富集条件.用原子吸收测金时改用水相喷雾,降低了火焰的背景,提高了信噪比和测量重现性,这对使用标尺扩展器极为有利.本法灵敏度为0.09μg/ml 1%H_2O.回收率94～107%.可测范围0.2～100克/吨金.
In recent years, there has been a means of protein-rich gold .Wu Shizuichou tofu brain enrichment of water with gold, kamel and other electrophoresis using high blood and serum gold protein gel. However, their test is limited to In a slightly acidic solution; this enrichment method has not been used for ore analysis. We tested the possibility of gold enrichment with animal proteins (eggs, duck eggs or goose eggs) Water or hydrochloric acid - hydrogen peroxide solution enrichment conditions.Atomic absorption test gold instead use aqueous spray, reducing the flame background, improve the signal-to-noise ratio and measurement reproducibility, the use of scale extender extremely The sensitivity of this method is 0.09μg / ml 1% H_2O, the recovery is 94 ~ 107%, the measurable range is 0.2 ~ 100g / t gold.
