✦ Synopsis

The fluorescence system of Al-BPMPHD-CTMAB was studied. Experiments showed that Al 3+ could form an ionic associate with BPMPHD and CTMAB. The compound could enhance the natural fluorescence of BPMPHD, upon which a new fluorescence method was put forward for determining Al 3+ . Under optimum conditions, a linear relationship was obtained between the fluorescence intensity and the Al 3+ concentration in the range 2.0 × 10 -6 -1.0 × 10 -4 mol/liter. The detection limit was 4.4 × 10 -8 mol/liter.
