摘要: 在不需外加还原剂的条件下一步原位合成了磺化硫杂杯[4]芳烃修饰的纳米金,并将其作为比色探针对金属离子进行检测。研究表明,磺化硫杂杯[4]芳烃修饰的纳米金能够选择性的识别CrP3+P,其检测限可达到1μM。

关键词: 磺化硫杂杯[4]芳烃, 金纳米粒子, Cr3+, 比色检测

Abstract: Thiacalix[4]arene tetrasulfonate modified gold nanoparticles which were used as a colorimetric probe for detection of metal ions were synthesized in situ by one step without external reducing agent. The results show that thiacalix[4]arene tetrasulfonate modified gold nanoparticles is capable to detect CrP3+P with high selectivity, and the detection limit is 1μM.

Key words: Thiacalix[4]arene tetrasulfonate, Gold nanoparticles, Cr3+, Colorimetric detection
