Abstract

A simple and sensitive spectrofluorimetric method for the determination of Al(III) based on the formation of Al-Morin-Triton X-100 ternary complex is described. The effect of other non-ionic surfactants, such as Tween 80, Tween 20 and octylglucoside (OG) on fluorescence analysis were also studied. The addition of Triton X-100 makes feasible the fluorimetric determination of submicrogram quantities of Al(III). The complex was excited at 410 nm and the fluorescence signal was measured at 495 nm. Maximum fluorescence signal was produced at pH 4.0 (acetic acid-acetate buffer), with 0.6% Triton X-100 and 1.35 × 10-3 mol L-1 Morin. The calibration graph is linear up to 7 mg L-1 and the detection limit is 0.022 mg L−1. The relative standard deviation is 1.81% for Al(III) at 5 mg L-1. It was found that Zn(II) and F- produced highest interference.
