“…Moreover, it can be noticed that, except for Cd, the estimated LOD and LOQ for MIP OES are lower (or very close to for Cu) than for ICP OES. Such observations, for various elements, have been reported by several authors: Li et al [5] for Mn, Zhao et al [6] for Ni and Pb, or Donati et al [2] for Cr, Ni, and Pb. Donati et al [2] proposed several hypotheses to support such observations.…”

Microwave-induced plasma optical spectrometry (MIP OES) and induced coupled plasma optical spectrometry (ICP OES) were implemented in parallel for the determination of Cd, Cu, Cr, Ni, Pb, and Zn in sediments, as well as in unexplored matrices such as sewage sludge and fired brick. Initially, a microwave-assisted digestion procedure was applied to solubilize the samples. A selective approach has recommended for the detection of elements with low and high concentration ranges in different environments to improve sensitivity. Limit of detection (LOD) and limit of quantification (LOQ) were found between 0.026-0.039 mg L −1 and 0.08-0.11 mg L −1 , respectively. Precision and trueness were controlled using certified reference materials with the same matrices for all analysts. MIP OES showed results in accordance with ICP OES and LOD in the same range (or better, i.e., Pb) than ICP OES. MIP OES found a potential alternative with comparable performance and reduced costs for the analysis of trace metals.

“…Studies comparing the results obtained by MIP OES and other techniques are, however, rather few, particularly when focusing on the elements Cd, Cr, Cu, Cd, Ni, Pb, and Zn. A few studies offer comparisons with the results obtained by ICP OES [5,6], but again, the number of analytes and/or matrices and is often restricted.…”

“…Therefore, quick and accurate identification of Cd(II) concentrations is urgent to prevent soil pollution and ensure food safety. Up to now, the regular methods have been employed for Cd(II) determination, such as X fluorescence spectrometry (XRF) [ 12 ], Atomic Absorption Spectroscopy (AAS) [ 13 ], Atomic Emission Spectrometry(AES) [ 14 ], Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES) [ 15 ], Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) [ 16 ], Atomic Fluorescence Spectrometry (AFS) [ 17 ], biological technique [ 18 ] and electrochemical method [ 19 ]. However, the spectrographic methods are not suitable for in-situ analysis because of complex operation, large volume, and expensive instruments.…”

The quality and safety of agricultural products are threatened by heavy metal ions in soil, which can be absorbed by the crops, and then accumulated in the human body through the food chain. In this paper, we report a low-cost and easy-to-use screen-printed electrode (SPE) for cadmium ion (Cd(II)) detection based on differential pulse voltammetry (DPV), which decorated with ionic liquid (IL), magnetite nanoparticle (Fe3O4), and deposited a bismuth film (Bi). The characteristics of Bi/Fe3O4/ILSPE were investigated using scanning electron microscopy, cyclic voltammetry, impedance spectroscopy, and linear sweep voltammetry. We found that the sensitivity of SPE was improved dramatically after functionalized with Bi/Fe3O4/IL. Under optimized conditions, the concentrations of Cd(II) are linear with current responses in a range from 0.5 to 40 µg/L with the lowest detection limit of 0.05 µg/L (S/N = 3). Additionally, the internal standard normalization (ISN) was used to process the response signals of Bi/Fe3O4/ILSPE and established a new linear equation. For detecting three different Cd(II) concentrations, the root-mean-square error using ISN (0.25) is lower than linear method (0.36). Finally, the proposed electrode was applied to trace Cd(II) in soil samples with the recovery in the range from 91.77 to 107.83%.

ABSTRACT. In this study, the method development is described for the multi elemental determination of organic rich soil reference material (BCR 700) by the new microwave plasma atomic emission spectrometry (MP-AES). Two sample preparation methods were compared (open vessel digestion on a hot plate and closed vessel microwave assisted digestion) for the BCR sample and EDTA extraction was carried out. The recoveries were tested by MP-AES and inductively coupled plasma optical emission spectrometry (ICP-OES) method to investigate whether the more cost-effective nitrogen supplied microwave plasma is appropriate for the elemental determination of digested organic rich soil samples. The BCR 700 sample was not certified for digestion methods yet similar sample pretreatment is present in the literature with which a good agreement was found. Our results also correlated with the values provided in the certification of the BCR 700 material for EDTA extraction. It was found that the microwave plasma is an effective and lowcost alternative of ICP-OES for soil analysis and with the convenient atmospheric digestion even the organic rich soil samples can be prepared prior to the elemental determination. However, the microwave assisted digestion is faster and easier to conduct. The limit of detection values of the measured elements by MP-AES are sufficiently low for the micro element determination of soils (Cd 70 µg kg -1 , Cr 5 µg kg -1 , Cu 25 µg kg -1 , Mn 12.5 µg kg -1 , Ni 45 µg kg -1 , Pb 220 µg kg -1 , Zn 155 µg kg -1 ).
