Sodium(I)-doped graphitic carbon nitride with appropriate interlayer distance as a highly selective sorbent for strontium(II) prior to its determination by ICP-OES

Deposition of triazine-based graphitic carbon nitrideviaplasma-induced polymerisation of melamine

“…S3†), the product is thermally very robust. Other than polymeric HGCN, 50–52 the deposited material is still stable at 800 °C. The film is characterised by a noticeably matt appearance (see Fig.…”

Advanced materials on sample preparation for safety analysis of aquatic products

“…Graphitic carbon nitride is a new 2D graphene analogue with abundant in-built N-rich functional groups and electronic delocalization properties [28], which has been widely applied for the separation and enrichment of metal ions and organic aromatic compounds [51][52][53]. Shi et al [51] developed Fe 3 O 4 /g-C 3 N 4 nanocomposite as adsorbent for ultrasound-assisted dispersive μ-SPE and quantitive analysis of Hg(II) by coupling with atomic fluorescence spectroscopy ( Figure 2).…”

“…This method with wider linear range of 0.005-0.4 mg/L, and the LOD of the proposed method was 1.4 ng/L. Kang et al [52] prepared multilayered and porous sodium-doped graphitic carbon nitride (GCN-Na) as SPE media for sampling Sr(II). GCN-Na exhibited excellent enrichment capacity and selectivity to Sr(II), since the Na(I) doped turned the small interplanar stacking distance to match the size of Sr(II).…”

Simultaneous determination of lead and copper in Polygonatum kingianum by ICP OES combined with natural deep eutectic solvent-based magnetic dispersive micro solid phase extraction

“…At present, the atomic spectrometric analysis methods used in the determination of metal elements include inductively coupled plasma optical emission spectrometry (ICP OES), 4,5 inductively coupled plasma mass spectrometry (ICP-MS), 6,7 flame atomic absorption spectrometry (FAAS), 8,9 graphite furnace atomic absorption spectrometry (GFAAS), 10,11 electrothermal atomic absorption spectrometry (ETAAS) 12,13 and so on. However, due to the complexity of the sample matrix and the difficulty of detecting trace contaminant elements, the combination of advanced sample separation and preconcentration methods and atomic spectroscopy is a more effective strategy for the analysis of trace elements.…”
