半胱氨棉吸附—原子吸收法测定地质样品中的微量金
DETERMINATION OF TRACE GOLD IN GEOLOGICAL SAMPLE BY USING ATOMIC ABSORPTION SPECTROMETRY WITH CYSTEINE COTTON
【摘要】 本文介绍用半胱氨棉在5MHCl—pH5介质中富集地质样品中的微量金,常见的18种共存离子用柠檬酸能消除对吸附金的干扰。对吸附速度和半胱氨棉用量的研究,得到操作简便、快速易于掌握的方法。
【Abstract】 This paper presents reserch condition of trace gold in geological sample of quantitative absorption from 5M HCl to pH5 by cysteine cotton.The Co-existen ions eliminates for gold absorption interference using citrate andabsorption rate were discussed.By this method the recoveries for gold were 95.8-101.4%. The velative stan dard deviations were ±3.5%.
