基于纳米二氧化钛-磷酸十六烷基酯(DHP)薄膜修饰电极，研制了一种灵敏、方便地测定五氯苯酚(PCP)的电化学传感器。由于纳米二氧化钛具有巨大的比表面积、较强的吸附能力、微妙的电学性质和催化能力等独特的性质，使得五氯苯酚在纳米二氧化钛/DHP电化学传感器上的电化学氧化信号显著增强，表明纳米二氧化钛薄膜对五氯苯酚的测定具有明显的增敏作用。在此基础上，建立了一种灵敏、简便的测定五氯苯酚的电化学方法。该传感器的线性范围为5.0×10−8molL−1~7.5×10−6molL−1，线性范围为1.5×10−6molL−1~1.0×10−4molL−1，检出限为1×10−8molL−1。
An electrochemical sensor for sensitive and convenient determination of pentachlorophenol (PCP) was developed based on the nano-TiO2-dihexadecylphosphate (DHP) film thin film-modified electrode. Owing to the unique properties of nano-TiO2such as huge surface area, strong adsorptive ability, subtle electronic properties and catalytic ability, the electrochemical oxidation signal of PCP significantly increases at the nano-TiO2/DHP-based electrochemical sensor, suggesting that nano-TiO2film exhibits obvious enhancement effect to the determination of PCP. Based on this, a sensitive and convenient electrochemical method was developed for the determination of PCP. The linear range is over the range from 5.0×10−8molL−1to 7.5×10−6molL−1and from 1.5×10−6molL−1to 1.0×10−4molL−1with a limit of detection of 1×10−8molL−1. Finally, this sensor was successfully employed to detect PCP in water samples.
