The stability of lead(II) thiocyanate complexes and the extraction behavior of lead(II) in 1 mol dm<SUP>−3</SUP> Na(SCN, ClO<SUB>4</SUB>) were studied. By an extraction method with thenoyltrifluoroacetone, logβ<SUB>1</SUB>=0.49 was obtained for PbSCN<SUP>+</SUP>. The extraction was poor with 4-methyl-2-pentanone but effective with trioctylphosphine oxide in hexane. Not only Pb(SCN)<SUB>2</SUB> but also Pb(SCN)(ClO<SUB>4</SUB>) and Pb(ClO<SUB>4</SUB>)<SUB>2</SUB> were extracted into both of the solvents.
