In-situ formation of a solid adsorbent for the extraction of some metal ions from crude oil before their determination by microflow nebulizer inductively coupled plasma-mass spectrometry

Atomic spectrometry update: review of advances in the analysis of metals, chemicals and materials

“…Altuwaijari et al developed a new sample preparation approach for the extraction of metal ions from crude oil prior to their quantification using ICP-MS . 94 The extraction procedure was based on dispersive solid phase extraction in which dithiooxamide particles were produced in situ and used as the adsorbent. To achieve high extraction efficiency the sorbent was first dissolved in an organic solvent and then injected into the diluted sample.…”
