Abstract:
With the acceleration of industrialization,the issue of heavy metal pollution has become increasingly severe,and the potential threat to the ecological environment and human health is increasing.It is necessary and important to detect the contents and species of heavy metal ions.To reduce the influence of complex sample matrices and enrich low contents of analytes,suitable sample pretreatment is usually required before analysis.In recent years,magnetic solid phase extraction(MSPE)based on magnetic extraction materials prepared by rational design and functional modification have attracted much attention in the analysis of heavy metal ions due to their high selectivity,satisfactory adsorption capacity and efficient separation ability.In this paper,the application progress of magnetic composite materials based on ion imprinted polymers,chitosan,metal organic frameworks,ionic liquids and other polymers in the extraction of heavy metal ions from environmental water samples,seafood,radioactive waste and food in recent years was reviewed.The current review focused on the preparation of representative materials in the same category and their adsorption performance towards heavy metal ions.The challenges were analyzed and the future development trend was also prospected.
