对氯硝基苯(PCNB)的广泛存在对环境机构和人类健康造成了严重的影响，因此对PCNB的定量和定性检测非常重要。本文通过简单的超声波作用制备了一种新型的由碳纳米角和碳纳米管组成的三维纳米杂化材料(CNH-CNT)，并将其用于修饰电极，用于PCNB的电化学传感。结果表明，在优化的条件下，由于碳纳米管与碳纳米管的协同作用，碳纳米管与碳纳米管具有良好的电化学传感性能，对五氯苯酚的检测线性范围为0.1~70.0μM，检测下限为5.9 nm。最后，将该方法成功地应用于实际水样中多氯联苯的测定。
The widespread presence of para-chloronitrobenzene (PCNB) has caused serious impacts on the environmental agencies and human health, hence the quantitative and qualitative sensing of PCNB is very important. Herein, a novel three-dimensional nanohybrid composed of carbon nanohorns and carbon nanotubes (CNH–CNT) was prepared via a simple ultrasonication process, and then, the obtained CNH–CNT nanohybrid was used to modify an electrode for the electrochemical sensing of PCNB. Under the optimized conditions, the results showed that the CNH–CNT nanohybrids could exhibit electrochemical sensing performance toward PCNB detection due to the synergetic properties of CNHs and CNTs, and a wide linear range from 0.1 to 70.0 μM and a low detection limit of 5.9 nM were obtained for the determination of PCNB. Finally, the developed method was successfully applied in the determination of PCNB in real water samples.
