基于手性金纳米粒子圆二色光谱法识别与检测银离子
Recognition and Detection of Silver Ion by Circular Dichroism Spectrum Based on Chiral Gold Nanoparticles
摘要
Abstract
In this work,chiral gold particles with optical activity can be obtained by a facile liquid phase method.The textural proper-ties of the as-prepared samples were characterized by high resolution transmission electron microscopy,circular dichroism spectrum and absorption spectrum.The results show that the average particle size for the production is 3.6 nm and silver ion can be selectively recognized from 1 3 kinds of metal ions in 1 2 min with universal recurrence.We also established the standard curve for detecting silver ion.This study demonstrates that the linear range for this curve is 0.2-30μmol/L,the linearly dependent coefficient is 0.995(n=15),which supplies a simple new environmentally friendly method for quickly detecting and recognizing silver ion in environmental water samples with high precision.关键词
