磺化杯[6]芳烃修饰的金纳米粒的合成及其对多环芳烃的比色检测

Preparation and Colorimetric Detection of Polycyclic Aromatic Hydrocarbons by para-Sulfonatocalix[6] arene-modified Gold Nanoparticles

通过偶联修饰的方法合成了水溶性磺化杯[6]芳烃修饰的金纳米粒,并研了其对多环芳烃的比色检测.结果表明,磺化杯[6]芳烃修饰的金纳米粒对蒽具有良好的识别选择性.该比色探针对蒽的检测限可达到2×10-6mol/L.这种比色传感器能够实现现场原位检测.

The para-sulfonatoealix[ 6] arene-modified gold nanopartieles were synthesized as the probes of polycyclic aromatic hydroarenes（PAHs） in aqueous solution. The results show that p-SC6-Au NPs could be used to probe anthracene, selectively. The detection limit（3δ） is 2 × 10^-6 mol/L. This colorimetric sensor can be used to probe anthracene in situ.
