TI  - Simultaneous determination of tetrathiomolybdates and molybdates in spiked blood 
      plasma by differential pulse voltammetry and their speciation.

AB  - A selective, sensitive and reliable voltam- metric method for the simultaneous 
      determination of MoS(2-)(4) and MoO(2-)(4) has been developed. The reduction of 
      HgMoS(4) at -0.43 V and the reduction of Mo as complex of MoO(2)-oxine(2) at 
      -0.63 V in acetate buffer at pH 4.9 are utilized for the simultaneous 
      determination by differential pulse cathodic stripping voltametry (DPCSV). 
      Cadmium and lead form complexes with MoS(2-)(4), but do not interfere with the 
      determination. The limit of detection is 0.59 microg/l Mo for MoS(2-)(4) and 1.8 
      microg/l Mo for MoO(2-)(4). The R.S.D at a concentration level of 20 microg/l is 
      4.7% for MoO(2-)(4) and 3.6% for MoS(2-)(4). The method is applied to spiked 
      blood plasma samples for the determination of free tetrathiomolybdates and 
      molybdates. Additionally, labile tetrathiomolybdates and molybdates can be 
      determined in spiked blood plasma after treatment of the sample with 0.15 mol/l 
      KCN and ultrafiltration.
