Abstract
A rapid, simple and inexpensive spectrofluorimetric method has been developed for the simultaneous identification and quantification of anthracene (ANT), 9,10-dimethylanthracene (DIM), 2-aminoanthracene (AMI) and dibenz[ah]anthracene (DIB). A well-resolved spectrum for the mixture of these four compounds is obtained based on a single non-linear variable-angle synchronous scanning. The linear concentration ranges are 10–1000, 5–500, 50–1000 and 10–200 ng mL–1 for ANT, DIM, AMI and DIB, respectively, at λex/λem = 358/380, 399/408, 414/465 and 298/394 nm, respectively. The analyses are performed in cyclohexane. Recoveries of 90.0–111.0% in synthetic mixtures are obtained. The detection limits are 2.0 ng mL–1 for DIM, 2.7 ng mL–1 for ANT, 15.8 ng mL–1 for AMI and 4.2 ng mL–1 for DIB. The method has also been applied to several real water samples with satisfactory results.
