摘要
本文提出以MBT—MIBK体系从2％HNO_3介质中萃取银,有机相进样,火焰原子吸收测定银的新方法。该法用于测定地质样品和水样中的银,效果令人满意。
A new method of the determination of trace silver by FAAS after extracting Ag(I) from 2% HNO2 medium with MBT-MIBK system and sampling of the organic phase was established.This method has been used in the determination of trace silver in geological samples and environmental waters with successful results.
