Abstract:
A simple, rapid and economical method for measurement of hydroquinone was
developed. Hydroquinone can reduce Fe(III) to Fe(II). The remaining Fe(III) later reacts with
thiocyanate to yield a colored complex. Therefore, the hydroquinone concentration in excess
of that necessary to form the liberated complex can be determined spectrometrically. In this
work, a commercial spectrophotometer and paired emitter detector diodes (PEDD) fabricated
in-house were used as a detector. A linear range of 5-100 and 10-100 μM for quantification
of hydroquinone was achieved using spectrophotometer and PEDD, respectively. Superior
precision of analysis was attained for both detectors (relative standard deviation < 0.2%).
Each measurement required 3 min, offering high sample throughput. Moreover chemicals
used in the method are inexpensive. The developed method was applied for screening
hydroquinone in whitening agents. The results were consistent with those obtained using the
phenanthroline method. Analytical recoveries were found to be in an acceptable range,
indicating no interference by other cosmetic ingredients. Furthermore the PEDD is portable,
enabling on-site analysis.
