摘要
采用火焰原子吸收光谱法直接测定多金属矿中高含量的银,其程序是将样品于700℃高温炉中灼烧1小时,以王水溶矿,在硫脲介质中利用仪器的参比工作方式直接测定样品中银的含量,无需稀释样品溶液,减少了误差。该法简便、快速,结果准确。
High content silver in polymetallic ore was directly determined by flame atomic absorption spectrometry. The procedures are burning the sample at 700℃ in a high temperature stove for 1 hour, dissolving the sample with aqua regla then directly determining the silver content in thiourca medium with a flame atomic absorption spectrometer in the reference mode. It does not need sample dissolving, reducing the error. This method is simple, fast and accurate.
