Abstract

Abstract The present study describes a facile and environmentally friendly hydrothermal method for the fabrication of metal decorated silica-based core-shell magnetic nanocomposite M@Si-MNCs, applied as a sustainable coating material for the solid-phase microextraction of toxic cadmium ions. M@Si-MNCs were characterized by scanning electron microscopy, X-ray-diffraction, Fourier transform infrared spectroscopy and Brunauer–Emmett–Teller analyzer. Relevant parameters have been studied to obtain maximum recovery, including pH, adsorbent dosage, model solution volume, - adsorption and desorption time, and matrix effects. The developed method obtained excellent linearity from 50 to 500 µg/L with a limit of detection of 1.2 µg/L and a limit of quantification of 4.1 µg/L. The new method was applied for separation, preconcentration and determination of cadmium in environmental and tobacco samples.

金属修饰二氧化硅核壳磁性纳米复合材料固相微萃取镉（Ⅱ）的高分辨率连续源火焰原子吸收光谱测定

摘要:本研究描述了一种简单环保的水热法制备金属修饰的硅基核壳磁性纳米复合材料M@Si-MNCs，作为一种可持续的固相微萃取有毒镉离子的涂层材料。通过扫描电子显微镜、x射线衍射、傅里叶变换红外光谱和布鲁诺尔-埃米特-泰勒分析仪对M@Si-MNCs进行了表征。研究了pH、吸附剂用量、模型溶液体积、-吸附和解吸时间、基质效应等相关参数以获得最大回收率。该方法在50 ~ 500µg/L范围内线性良好，检出限为1.2µg/L，定量限为4.1µg/L。该方法可用于环境样品和烟草样品中镉的分离、富集和测定。

期刊介绍： Instrumentation Science & Technology is an internationally acclaimed forum for fast publication of critical, peer reviewed manuscripts dealing with innovative instrument design and applications in chemistry, physics biotechnology and environmental science. Particular attention is given to state-of-the-art developments and their rapid communication to the scientific community. Emphasis is on modern instrumental concepts, though not exclusively, including detectors, sensors, data acquisition and processing, instrument control, chromatography, electrochemistry, spectroscopy of all types, electrophoresis, radiometry, relaxation methods, thermal analysis, physical property measurements, surface physics, membrane technology, microcomputer design, chip-based processes, and more. Readership includes everyone who uses instrumental techniques to conduct their research and development. They are chemists (organic, inorganic, physical, analytical, nuclear, quality control) biochemists, biotechnologists, engineers, and physicists in all of the instrumental disciplines mentioned above, in both the laboratory and chemical production environments. The journal is an important resource of instrument design and applications data.
