银是人们熟知的最古老的金属之一。古代大量用作钱币、饰物和器皿。近代则因具有广泛的工业用途而成为现代工业重要的原料之一。由于世界银的产耗差一直较大,供不应求的局面造成国际市场银价的不断上涨,因而银的资源开发和生产受到国家重视。为了配合此项任务,对于银的分析方法也就相应地引起注意。本文查阅近年来国内外有关银的分离、富集手段和测定方法进行综合介绍以供参考。

In modern times, it became one of the important raw materials for modern industry due to its extensive industrial use. Due to the fact that World Bank’s production and consumption have been relatively great, the demand in short supply has caused the silver price in the international market to rise continuously.
