发射光谱法测定地质样品中Sn、Mo、 Ag等元素

DETERMINATION OF Sn、Mo、Ag ETC. ELEMENTS IN THE GEO-SAMPLE BY AES

采用发射光谱法,利用溶液作缓冲剂,通过氟化反应改变被测元素的蒸发行NH4F,为,一次完成对样品中W、Sn、Mo、Bi、Ag等多个元素的连续测定,快速、准确。

We used the AES and took the liquided NH4F as buffer, pass by fluorinating reaction, the evapration action of the elements determination can be changed. By which means ,to finished the 、、、、continuously determinate of WSn.MoBiAg etc. in geo-sample ,quickly and exactly.Key word: AES; NH4F as buffer; Geo-sample
