英文摘要: Abstract(#br)Functionalized melamine sponge based on β-cyclodextrin (β-CD) and graphene oxide (GO) as a new solid phase extraction (SPE) adsorbent, was developed for determination of malachite green (MG) in seafood, coupled with high-performance liquid chromatography (HPLC). The obtained sponge prepared by an easy method and simple step, is placed into a syringe to enrich quickly MG. The extraction procedure was further improved by investigating the effects of the experimental parameters on pre-enrichment of MG. The present method had been successfully applied to determination of MG from crayfish and squid sample and obtained satisfied recovery value (88.6–100.8%) with coefficient of variance below 2.6–9.2% ( n = 3), which indicated that the method was suitable for the analysis of MG in...
