| 摘 要： | 该文探索了用乙炔-空气火焰原子吸收分光光度法间接测定海水镁砂中硼的适宜条件。在弱酸介质中，硼砂、苯烃乙酸和[Cu(Phen)2]^2 缔合生成具有较大疏水集团的缔合物，用MIBK萃取，然后用火焰原子吸收分光光度法测定有机相中的铜，由此间接测定硼的含量。该方法操作简单快速，条件稳定，有良好的选择性和灵敏度。

| Abstract: | The suitable conditions of indirectly determining Boron in Magnesium Oxide made from sea water by FAAS are studied in this paper. In the media of a weak acid, Borax, Phenylhydroxyacetic acid and [Cu(phen) 2] 2+ form a hydrophobic grouping of association molecule, which is extracted by 4-methyl-2-pentanone. The content of Boron is indirectly determined by determining that ofCopper in the organic phase by FAAS. This method is of quick and simple operation, stable condition, high sensitivity and high sensitivity and high selectivity. |
