摘要

•Fenton oxidation is developed for selective dissolution of AgNPs.•Protein corona-induced extraction was proposed for preconcentration of Ag2S-NPs.•An ultrahigh enrichment factor of 10,000 was obtained for Ag2S-NPs.•The Ag2S-NPs extracted can remain in intact by means of the developed method.•Recoveries of 83.7−105% from real waters can be achieved for low-level Ag2S-NPs.
