摘要
本方法以氢化物分离,碘液吸收地质样品中的锑铋,然后,在DH1左右的NaAc-HCI缓冲溶液中,以DTPM为显色剂,用双波长分光光度法同时测定锑和铋。方法简单快速,选择性好,分析结果与原子荧光法吻合。
Antimony and bismuth in geological samples are separated as hydride which are absorbed with iodine solution,then followed by spectrophotometric detemination with DTPM in NaAc-HCl buffer solution of pH1. This determination is simple and rapid and of high selectivty.The analytical results are consistent with those of atomic fluorescence determination.
