| Abstract: | The reagent of 2,3,7-trihydroxy-9-（3,4-dihydroxy） phenylfluorone（3,4-DHPF）was synthesized.And the spectrophotometric properties were investigated.It was found that,3,4-DHPF formed an orangered（2∶ 1） complex with molybdenum（Ⅵ） in the buffer solution（pH5.0 of NaAc-HAc）,exhibiting an absorption maximum at 566 nm.The apparent molar absorptivity was 1.84×104 L · mol-1·cm-1,and Beer＇s law was obeyed in the range of 0～1.6 mg/L molybdenum（Ⅵ）. |
