The widespread use of silver nanoparticles (AgNPs) and gold nanoparticles (AuNPs) in a wide variety of industrial as well as medical sectors is indisputable. This leads to a new concern about their presence in various environmental compartments. Since their negative effect and potential toxicity impact have been confirmed, analytical chemists focus on the development of different procedures for their reliable detection, identification, characterization, and quantification, not only in homogenous and simple matrices but also in complex environmental matrices. However, nanoparticles and their ionic species can coexist and their toxicity may differ; therefore, novel analytical approaches are necessary to monitor not only the nanoparticles but also their ionic species. The aim of this article is to bring a review of recent works where magnetic solid-phase extraction (MSPE) procedures in connection with spectrometric methods were used for separation/preconcentration and quantification of (1) silver and gold ions in various environmental samples, (2) AgNPs and AuNPs in real water samples in the presence of various coexisting ions, and (3) both species (it means Ag ions and AgNPs; Au ions and AuNPs) in real water samples. The results presented herein show the great analytical potential of MSPE procedures in connection with spectrometric methods used in these fields and can be helpful in guiding analytical chemists who aim to work on this subject.

磁性固相萃取作为金属纳米粒子及其离子种类快速分离的有前途的技术：近期进展的综述。

毫无疑问，银纳米颗粒（AgNPs）和金纳米颗粒（AuNPs）在各种工业和医疗领域中的广泛使用是不争的。这引起了人们对它们在各种环境隔室中的存在的新关注。由于已经确认了它们的负面影响和潜在的毒性影响，分析化学家不仅致力于在均质和简单的基质中，而且在复杂的环境基质中，都致力于开发不同的方法以进行可靠的检测，鉴定，表征和定量。但是，纳米粒子及其离子种类可以共存，其毒性可能不同。因此，新颖的分析方法不仅需要监测纳米颗粒，还需要监测其离子种类。本文的目的是回顾一下最近的工作，其中将磁性固相萃取（MSPE）程序与光谱方法结合使用，以分离/预浓缩和定量（1）各种环境样品中的银和金离子，（ 2）在存在各种共存离子的情况下，真实水样中的AgNPs和AuNPs，以及（3）真实水样中的两种物质（表示Ag离子和AgNPs； Au离子和AuNPs）。本文提供的结果显示了MSPE程序与这些领域中使用的光谱测定法相关的巨大分析潜力，并且有助于指导致力于此课题的分析化学家。
