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。
In this paper, we propose a new method of extracting silver from 2% HNO_3 medium by MBT-MIBK system, sampling the organic phase and determining the silver by flame atomic absorption spectrometry. The method is used to determine the geological samples and water samples of silver, the effect is satisfactory.
