A stir-bar sorptive extraction coating based on chemically bonded silica for the analysis of polar organic compounds and heavy metal ions

摘要

The new stir-bar coating based on silica gel modified with ketoimine groups was applied to the preconcentration of phenolic endocrine disruptors and heavy metal ions such as Cu~(ii), Cr~(iii) and N~(iii) in water samples followed by determination using LD-GC/MS and ICP-OES, respectively.
