Biomimetic mercury immobilization by selenium functionalized polyphenylene sulfide fabric.

ABSTRACT: Highly efficient decontamination of elemental mercury (Hg⁰) remains an enormous challenge for public health and ecosystem protection. The artificial conversion of Hg⁰ into mercury chalcogenides could achieve Hg⁰ detoxification and close the global mercury cycle. Herein, taking inspiration from the bio-detoxification of mercury, in which selenium preferentially converts mercury from sulfoproteins to HgSe, we propose a biomimetic approach to enhance the conversion of Hg⁰ into mercury chalcogenides. In this proof-of-concept design, we use sulfur-rich polyphenylene sulfide (PPS) as the Hg⁰ transporter. The relatively stable, sulfur-linked aromatic rings result in weak adsorption of Hg⁰ on the PPS rather than the formation of met
