A Natural Deep Eutectic Solvent–based Ultrasound-Vortex-assisted Dispersive Liquid–Liquid Microextraction Method for Ligand-less Pre-concentration and Determination of Traces of Cadmium Ions in Water and Some Food Samples

Atomic spectrometry update: review of advances in the analysis of clinical and biological materials, foods and beverages

“…Chemometric tools, such as LDA, LR, kNNs, NB, NNs, PLS-DA, RF and SVMs, were used to build prediction models. For both origin and cultivation discrimination 200 Hg, 202 Hg, 97 Mo, 98 Mo, 23 Na, 60 Ni, 118 Sn, 205 Tl, and 232 Th were found to have no signicant impact on the models. For assessment of cultivation only 107 Ag, 137 Ba, 43 Ca, 44 Ca, 24 Mg, and 66 Zn were required to discriminate between eld and forest grown samples.…”

Atomic spectrometry update: review of advances in atomic spectrometry and related techniques

“…The LOD and LOQ were 1.6 and 5.0 ng L −1 respectively, with an enrichment factor of 166× and 91.3% recovery. A similar approach, using ETV-AAS, was adopted by Shamsipur et al , 12 who used a DE solvent prepared from salicylic acid and l -menthol for the extraction of Cd from water and food samples. They achieved an LOD and LOQ of 0.37 × 10 −4 and 1.24 × 10 −4 μg L −1 respectively, with a preconcentration factor of 125×.…”

Natural Deep Eutectic Solvents (NADESs) Combined with Sustainable Extraction Techniques: A Review of the Green Chemistry Approach in Food Analysis

“…The performed extraction technique was favorably applied to the separation and determination of ultra-traces of cadmium in several food and water samples. Among the used determination tools, graphite furnace atomic absorption spectrometry (GFAAS) was established as a highly efficient technique for the determination of the concentration of various metal ion species [101].…”
