| 要約: | Nitrobenzene (NB) is a volatile organic compound (VOCs) produced in large quantities for industrial use, is highly toxic and repeated exposure can cause severe damage to human health. The traditional methods for the determination of NB reach concentrations of parts per million, but this pollutant in water is below these concentrations. Due to this it is important the development of new sensors for the determination of NB in water. In this work an electrochemical sensor was developed for the determination of NB with single crystal rutile TiO2 nanorods. Synthesis parameters were modified to obtain desired morphologies and were characterized by Raman spectroscopy, SEM, EDS and electrochemical techniques. Quantification of NB was performed by cyclic voltammetry (VC). The sensitivity and detection interval of the probes increase with increasing the opening of the TiO2 nanoflowers, reaching concentrations below the parts per billion. As conclusion of this work is that the electrochemical properties in the detection of NB by TiO2 nanoflowers are directly related to the conditions of synthesis used. The findings of this study have a number of valuable implications for future studies of VOC monitoring. |
