Abstract

The extraction equilibrium of mercury(II) from aqueous ammonium thiocyanate solution with triisobutyl-phosphine sulfide(=TIBPS=S¯) in toluene has been measured at 303 K. It was found that mercury(II) is extracted according to a solvation reaction by TIBPS as a mercurydl) :TIBPS 1:2 complex, Hg(SCN)₂S2, as follows: The extraction equilibrium constant, K_e, was evaluated as K_e = 1.8 × 10⁶ (dm³/mol)².
