А.С.Бажов和Е.А.Соколова(1977)提出过在同一份样品中用二苯硫脲萃取分离后测定金、银含量(10~(-5)—10~(-4))的原子吸收方法。但是为了满足地球化学找矿方法的需要,当前迫切的任务是制定出可以同时测定金、银克拉克含量(10~(-7)—10~(-8)％)的快速原子吸收方法。这一问题是有可能顺利解决的,因为一方面最近获得了关于焙烧分析样品时银无明显损失的资料,另一方面是有了与二苯脲不同的有效萃 А.С.Бажов and Е.А.Соколова (1977) proposed the determination of gold and silver (10 -5 - 10 -4) after extraction with diphenylthiourea in the same sample Atomic absorption method. However, in order to meet the needs of geochemical prospecting methods, an urgent task is to develop a rapid atomic absorption method that can simultaneously determine gold and silver cokes content (10 -7 -10 -10 -8%). This problem is likely to be solved because, on the one hand, there has recently been obtained information on the absence of appreciable loss of silver in the case of roasting and on the other hand an effective extraction
