| titleOfInvention | Preparation of an ionic liquid-coated aminosilanized magnetic graphene oxide composite and its application in heavy metals |
| abstract | The invention relates to a method for enriching and extracting three kinds of heavy metal ions in shellfish samples and simultaneously measuring the content; in particular, it relates to an aminosilanized magnetic graphene oxide (MGO@SiO 2 ‑APTES‑IL) nanometer coated with ionic liquid. Preparation of composite materials and its application in the detection of three target heavy metals in shellfish samples; the present invention uses MGO@SiO 2 ‑APTES‑IL as an adsorbent, and uses dispersive magnetic solid-phase microextraction (d‑MSPE) to analyze shellfish The samples were pretreated, and inductively coupled plasma mass spectrometry (ICP‑MS) was used as a detection tool to sensitively determine the target heavy metals: lead(II), copper(II) and cadmium(II); Extraction and enrichment of trace amounts of target heavy metal elements, while still showing good adsorption performance in multiple recycling. The invention researches and optimizes the main influencing factors affecting the adsorption and desorption of target heavy metal ions, the experimental results meet the requirements of high sensitivity and high accuracy, and provides a new method for the detection of three target ions in shellfish. |
