溶剂萃取和无焰原子吸收光谱相结合,可用于测定天然水中ppt级(微微克/毫升)的金。该方法分两步萃取,在盐酸存在的情况下生成HAuCl_4,经萃取进入小体积的甲基异丁基酮(MIBK)溶液中,这里
Solvent extraction in combination with flameless atomic absorption spectrometry can be used to determine ppt levels (pg / ml) gold in native water. The method is performed in two steps to produce HAuCl_4 in the presence of hydrochloric acid and extracted into a small volume of methyl isobutyl ketone (MIBK) solution where
