| Abstract: | The reaction of gallium with 8-hydroxyquinoline 5 sulfonic acid in presence of CTMAB has been studied. The triple coordination compound formed possesses λ ex =388 nm, λ em =506 nm. Beer′s law is obeyed in the range of Ga 0～0.56 mg/L with a relative standard deviation of 1.9% for a 0.0027% gallium solution and the recovery is 97.3%～102.0%. |
