Metal in extraction from perchlorate solutions with diantipyrylmethane

A comprehensive study of the extracting trace metal ions of I-8 groups of the periodic table from perchlorate solutions by diantipyrilmethane in dichloroethane depending on pH of water phase, is conducted. Quantitavely extracted aAe Cusup(2+), Znsup(2+), Cdsup(2+), Scsup(3+), Ysup(3+), Insup(3+), Zrsup(4+), Hfsup(4+), Pbsup(2+), Vsup(4+), Mnsup(2+), Fesup(3+), Tlsup(3+) and rare-earth elements. The influence of other parameters of the system (quantities of diantipyrilmethane and NaClO4) on the distribution of metal ions is studied referring to yttrium(3). The latter is extracted as the YR3(ClO4)3 complex which is supported by its preparative extraction
