[Study on the double fluorescers fluorometry and its application].
Abstract
Butylrhodamine B (BRB) was produced and entered into aqueous phase when pH=8.7 buffer solution was added to toluene extractive solution of GaCl4BRB+. And then BRB2 x TBF was extractred by tetrabromofluorescein (TBF). N-butanol (toluene:n-butanol 1:1) was added to toluene extractive solution of BRB2 x TBF. The sensitivity was raised because of the assistant effect of BRB2 x TBF. The detection limit was 0.1 microg/L. Beer's law was obeyed in the range of 0-0.15 mg/L with a relative standard deviation of 3.9% for 0.0027% gallium in metal and the recoveries were 94.7%-105.2%.
