Method for removing platinum and palladium in liquid

摘要

PPROBLEM TO BE SOLVED: To efficiently separate a first platinum group (Pt and Pd) and a second platinum group (Ru, Os, Rh and Ir) from a solution containing platinum group (Pt, Pd, Ru, Os, Rh and Ir). PSOLUTION: In the method for recovering the second platinum group Ru, Rh, Ir and Os from a platinum group solution, Se is added to the solution containing Pt, Pd, Ru, Rh, Ir and Os to reduce the Se with SOSB2/SB, thereby coprecipitating and removing only Pt and Pd together with the Se.
