Synchronized detection and removal of thiols using a Gd(OH)3nanosheet-sodium pentacyanonitrosylferrate(II) complex

Abstract

We described a novel procedure for visible detection and separation of thiols and disulfides. The method uses a Gd(OH)₃ nanosheets–sodium pentacyanonitrosylferrate(II) paramagnetic complex which produce an intermediate chromophore when coupled with a sulfur containing analyte, which is detectable with the naked eye and simultaneously can be removed by applying an external magnetic field.
