测定银的方法有高温石墨炉原子吸收光谱法和巯基棉富集高碘酸钾吸光光度法[1] ,但前者受仪器设置的限制 ,不易普及 ,后者由于水中银含量很低 ,往往受灵敏度的限制 ,需要富集 ,必须向水样中加入许多试剂 ,操作比较复杂 ,易造成误差。本文采用加热浓缩[2 ] 火焰原子吸收光谱法 ,
The method for the determination of silver by high temperature graphite furnace atomic absorption spectrometry and sulfhydryl cotton enrichment potassium periodate spectrophotometry [1], but the former is limited by the instrument set, not easy to popularize, the latter because of low silver content in water, often by Sensitivity limits, the need to enrich, you must add a lot of reagents to the water sample, the operation is more complicated, easy to cause errors. In this paper, heat concentration [2] flame atomic absorption spectrometry,
