摘要： 在pH=3.1的HCOOH-HCOONa缓冲液中,磷钼酸粒子在450 nm处产生一个共振瑞利散射(RRS)峰。金纳米粒子(AuNPs)可催化磷钼酸-甲酸反应生成磷钼蓝,使得450 nm处磷钼酸的RRS强度线性降低。Hg2+可与AuNPs发生电置换反应,从而抑制AuNPs的催化作用,RRS峰增强。在2.5×10-4～3.5 μmol/L,随着Hg2+浓度的增加,AuNPs的催化作用逐渐减弱,反应液的颜色逐渐从蓝色变为无色,体系在450 nm处的RRS峰值(ΔI)线性增高,其线性方程为ΔI=0.32C+46.1,检出限为0.18 nmol/L。该法用于废水中Hg2+的检测,结果令人满意。

Abstract: Phosphomolybdic acid particles have a resonance Rayleigh scattering (RRS) effect, which produces a RRS peak at 450 nm. In the HCOOH-HCOONa buffer solution at pH=3.1, gold nanoparticles (AuNPs) can catalyze the reaction of phosphomolybdic acid-formic acid to produce phosphomolybdenum blue, making the RRS intensity of phosphomolybdic acid linearly decrease at 450 nm. Hg2+ can undergo a galvanic replacement reaction with AuNPs, thereby inhibiting the catalytic effect of AuNPs. In the range of 2.5×10-4-3.5 μmol/L, as the concentration of Hg2+ increases, the catalytic effect of AuNPs gradually weakens, the color of the reaction solution gradually changed from blue to colorless, and the resonance Rayleigh scattering peak of the system at 450 nm increases linearly. The regression equation is ΔI=0.32C+46.1, and the detection limit is 0.18 nmol/L. This method is used for the detection of Hg2+ in wastewater, and the results are satisfactory.

Key words: mercury, nano-gold catalytic, galvanic replacement, phosphorus molybdenum blue, resonance Rayleigh scattering
