Introduction

Inductively Coupled Plasma Mass Spectrometry (ICP-MS) is a widely accepted multi-element analytical technique for rapid and accurate detection of samples Trace elements. Compared with atomic absorption spectrometry and inductively coupled plasma atomic emission spectrometry (ICP-AES), inductively coupled plasma Mass spectrometry has many advantages, such as. matrix interference, high sensitivity, low detection limit. Carbon nanotubes (CNTs) have unique physical and chemical properties that have potential applications in many fields and have attracted a great deal of research interest. The use of chemical vapor deposition mass production of carbon nanotubes, the need to use metal particles as a catalyst [1-3]. Remove residual catalyst (eg Fe, Co, Ni) for the application of carbon nanotubes is of great significance [4]. After complicated purification steps, the catalyst content was determined. Due to gold The presence of a catalyst can be released with the use of carbon nanotubes, resulting in toxicological and ecological consequences of carbon nanotubes Ring [5-7]. In addition, the function of carbon nanotubes may depend on these catalyst impurities, so reliable techniques must be used to detect the impurity content. Current methods of analyzing the purity of carbon nanotubes include neutron activation analysis (NAA), transmission electron transport loss (EELS) (TEM), scanning electron microscopy (SEM) with energy dispersive X-ray spectroscopy (EDX), Raman spectroscopy, X-ray photoelectron XPS, TGA and XRF spectroscopy [8-12]. ISO /TC229 enacted some characterization of single-walled carbon Technical method standards for nanotubes and multi-walled carbon nanotubes, such as SEM (ISO /T S10798), TEM (ISO /T S10797), multi- Metric tube characterization method (ISO /T R10929). However, each detection method has its limitations. TGA can only reflect the change of mass under heated conditions, The impact of factors, including equipment, experimental conditions and sample factors, so the reliability of the test results is not high; neutron activation analysis is based on nuclear anti- Quantitative and qualitative methods should be used. The method has the advantages of high sensitivity, accuracy and precision, and can simultaneously measure trace, trace and main elements with sensitivity up to 10-6 ~ 10-9, therefore, often used as a standard reference formulation. However, due to the need for large nuclear reactor irradiation samples, neutron activation analysis Applications have been greatly limited, in addition, high cost and radiation hazards, longer analysis cycles, complex operating techniques, poor practicality, The application of neutron activation analysis method. Inductively coupled plasma mass spectrometry (ICP-MS) also has high sensitivity, accuracy and precision Degree, widely used in laboratory testing. It requires samples to be completely digested, and traditional digestion methods are suitable for soil, rock and biological sample analysis. Carbon nanotubes have an extremely stable structure, and metal residues may be encapsulated in the carbon shell structure, therefore, it is necessary to use a specific sample pre- Treatment [12-15]. Inductively coupled plasma mass spectrometry is better than graphite furnace atomic absorption spectrometry and inductively coupled plasma atomic emission spectrometry Has a higher sensitivity. This standard is the application of inductively coupled plasma mass spectrometry accurate detection of single-walled carbon nanotubes and multi-walled carbon nanotubes residual impurity elements, Provides the best sample preparation method. Appendix A is an example of method application. Determination of impurity elements in nanotechnology carbon nanotubes Inductively coupled plasma mass spectrometry
