Summary
A new spectrofluorimetric method enables rapid, simultaneous detection of four polycyclic aromatic hydrocarbons. This cost-effective technique accurately quantifies anthracene, dimethylanthracene, aminoanthracene, and dibenz[ah]anthracene in samples.
Area of Science:
- Analytical Chemistry
- Environmental Science
Background:
- Polycyclic Aromatic Hydrocarbons (PAHs) are environmental pollutants.
- Accurate quantification of PAHs like anthracene is crucial for environmental monitoring.
Purpose of the Study:
- To develop a rapid, simple, and inexpensive spectrofluorimetric method for simultaneous identification and quantification of four specific PAHs.
- To establish the analytical performance of the developed method, including linearity, recovery, and detection limits.
Main Methods:
- Utilized non-linear variable-angle synchronous scanning spectrofluorimetry.
- Analyzed mixtures of anthracene (ANT), 9,10-dimethylanthracene (DIM), 2-aminoanthracene (AMI), and dibenz[ah]anthracene (DIB) in cyclohexane.
- Determined specific excitation/emission wavelengths for each compound.
Main Results:
- Achieved well-resolved spectra for simultaneous analysis of the four PAHs.
- Established linear concentration ranges for ANT (10-1,000 ng mL⁻¹), DIM (5-500 ng mL⁻¹), AMI (50-1,000 ng mL⁻¹), and DIB (10-200 ng mL⁻¹).
- Obtained high recoveries (90.0-111.0%) and low detection limits (2.0-15.8 ng mL⁻¹).
Conclusions:
- The developed spectrofluorimetric method is effective for the simultaneous quantification of ANT, DIM, AMI, and DIB.
- The method demonstrates good accuracy and sensitivity, suitable for analyzing real water samples.
- This approach offers a rapid, simple, and cost-effective alternative for PAH monitoring.
