ABSTRACT Persimmon tannin (PT) was immobilized onto CoFe 2 O 4 @SiO microspheres to create a novel core–shell nanostructured magnetic bioadsorbent. The as‐designed @PT used recover Au(III) ions. bioadsorbent synthesis performed with different reaction times of 2, 4, 6, 12, and 24 h PT core weight ratio 0.8, 1.0, 1.2, 1.5, 2.0. profile adsorption by the material in aqueous medium investigated batch system. XRD, FTIR, TEM, thermal analysis, VSM were analyze materials. experiments conducted pH...
