A convenient and sensitive method to determine trace silver ( catalytic-XRF) is established, it is based on the catalytic effect of silver on decomposition of potassium permanganate in the medium of dilute nitric acid on illumination. 基于在稀硝酸介质中,光照时,银对高锰酸钾分解的催化作用,本文建立测定痕量银的简便、灵敏的方法&催化-XRF法。
For further enhancing silver leaching recovery, potassium permanganate is added in the pulp to leach out silver unwrapped by manganese dioxide. 为了进一步提高银的浸出率,在溶液中加入高锰酸钾,以浸出未被二氧化锰包裹的银。
