An optical fiber crystal violet sensor using a porous ITO membrane coated on an optical fiber surface with UV photon-enhanced sensitivity
Abstract
, which is much lower than the detection limit of traditional UV/Vis spectrometry for detecting this compound in aqueous sample solutions. The sensor was tested for analyzing crystal violet concentration in a pharmacy product, Gentian Violet, purchased from a local pharmacy store, and the obtained analytical results agree well with those obtained using a conventional UV/vis absorption spectrometry method. A standard addition/recovery test was also performed using tap water as the sample matrix to verify the effectiveness of the sensor for the quick analysis of crystal violet in water samples, and the obtained recovery rate ranged from 98.7% to 101%.
