Mixtures of boron and azomethine-H in solution result in slow complexation. Addition of sodium dodecyl sulfate (SDS), polyethylene glycol dodecyl ether (Brij-35), 4-(1,1,3,3-tetramethylbutyl)phenyl-polyethylene glycol (TritonX-100), and cetyltrimethyl ammonium bromide (CTAB) result in considerable decrease in complexation time and enhancement in signal of peak in solution and also sol-gel. The fluorescence of the complex is monitored at an emission wavelength of 486 nm with excitation at 416 nm. The presence of 1 x 10(-3) mol L-1 SDS decreased the complexation time up to 10 min in solution and 20 min in sol-gel for above 0.25 mu g B mL(-1) and 30 min in solution and 35 min in sol-gel for below 0.25 mu g B mL(-1). However, the photostability did not change by adding micelle in both media. The proposed method shows a linear response toward boron in the concentration range of 0.05-10 mu g mL(-1) and is selective for boron over a large number of electrolytes and cations. The detection limit was 7 mu g L-1. This method has been used for the detection of boron in environmental water samples and fruit juices with satisfactory results.
