摘要：

The compound (TNSTH) shows promise for extracting and separating the chloro-anions of Au(III) and Pd(II) from strong hydrochloric acid solutions (ca. 5M). The reagent may be used to separate precious metals from each other or from base metals. Most of the metals, with the exception of rhodium(III) and iridium(IV), can be stripped using a thiourea/HCl solution. TNSTH appears to be a chelating agent with donor N and S atoms.
