“…Spectral interferences, especially line overlaps, can be a major problem in ICP-AES. [35][36][37] Although efforts have been made to collect spectral interference data in different matrices [38][39][40][41] or to build in databases in commercial ICP-AES instruments to help users select emission lines free from spectral interference in different matrices, 42 the selection of an appropriate analytical line can still be difficult, especially for a sample with a complex or unknown matrix. Improper line selection results in a loss of detection power and analytical errors.…”

“…Therefore, determination of one REE in the presence of others in ICP-AES is a challenge with a relatively high likelihood of spectral interference. [38][39][40][41] The feasibility of using the plasma vertical profile to recognize spectral interferences among REEs was evaluated here with Ce II 302.279 nm emission as the matrix and Er II 302.273 nm emission as the analyte. The first ionization potentials of Ce (5.539 eV) and Er (6.108 eV) are similar, 45 as are the excitation energies, with 6.152 eV for the Ce II line and 6.256 eV for the Er II line.…”

Vertically resolved measurement of analyte emission was investigated as an on-line indicator for flagging matrix effects and system drift in inductively coupled plasma-atomic emission spectrometry. The method is based on the fact that plasma behavior and excitation conditions are heterogeneous along the ICP vertical axis. As a result, the relative magnitude and even the direction of the change in emission intensity caused by a matrix effect or system drift are not constant, but are functions of observation height in the plasma. Since the determined concentration of an analyte in a sample is proportional to the measured intensity, any change in matrix effects or system drift along the vertical profile will similarly shift the determined concentration, allowing the drift or interference to be detected. It was verified that the new method can successfully flag matrix interferences caused by a change in plasma conditions (so-called plasma-related matrix effects), a change in sample aerosol generation or transport (so-called sample-introduction-related matrix effects) or spectral interference from emission lines of the matrix. Similarly, the method responded effectively to system drift caused by a change in sample throughput, central-channel gas flow and plasma forward power.

“…The atomic spectra of lanthanides are complex. 29 Accordingly, the experimentally obtained spectrum was dense in peaks, showing that individual emission lines could be difficult to resolve. These peaks cannot be fully resolved owing to the resolution limit of the spectrometer.…”

A compact spark-induced plasma spectroscopic device was developed to detect elements used in a variety of applications. The system consists of a spark generator connected to tungsten electrodes, a custom-built delay generator, and two spectrometers that together cover the ultraviolet visible (UV–Vis) range (214–631 nm). The system was evaluated by qualitatively and quantitatively sampling copper standards. Prominent spectral peaks were identified using the NIST database for atomic emissions. The effectiveness of the proposed system was also tested with a lanthanide sample (gadolinium) and provided qualitative identification of the characteristic peaks. A semi-quantitative measurement for silicon and gold was performed using variable amounts of each particulate. Silica microbeads in solution were applied to paper wafers, while gold nanoparticles were sputter-coated onto silicon wafers. Results showed a positive correlation between the intensity of the signal and the concentration of each type of particulate. The variation of signal intensity was investigated to determine the repeatability, and the coefficient of variation was lowered from 60% to 25% after averaging measurements of multiple ablations per observation.

“…Wavelength interference and selection for the determination of rare earth elements: Each element has several characteristic lines which can interfered with each other when there are many elements [11][12][13] , usually characteristic lines with high sensitivity and little interference are selected to measure, the selected wavelength of rare earth elements of this study were showed in Table- Impacts of acidity on the test: 0.5, 1.0, 1.5, 2.0, 3.0 mol L -1 hydrochloric acid were taken to make a series of concentration of standard solution and detected at the above working conditions. The results showed that when the concentration of hydrochloric acid within 1-3 mol L -1 the emission spectra intensity of rare earth elements is essentially the same and strong.…”

To investigate spectral interference of La, Ce, Nd, Sm, Eu, Gd, Tb, Yb, Lu and Y when detecting by inductively coupled plasma-atomic emission spectroscopy (ICP-AES), different types of soils were digested with a mixture of HF + HNO3 + HCl by microwave digestion instrument and precipitated twice to remove most of the matrix elements. The results showed a good method with high sensitivity, strong antiinterference ability to determine these elements simultaneously. The results to detect the soil standard reference materials (GSS-4, GSS-5) showed that measured values are all in range the standard value allowed and consistent with the standard value, indicating that the method is accurate and reliable. The detection limit of each element range from 0.2-38.2 µg L-1 , the relative standard deviations were between 0.8 and 3.2 %. This method has been successfully applied to determine the content of rare earth elements in soil samples from orchards in southern Jiangxi and the distribution of rare earth elements in the different types of soil were explored.
