Abstract
The synergic extraction of Co(II) with 1-phenyl-3-methyl-4-benzoylpyrazol-5-one(HPMBP)in presence of acyclic polyethers Butex (dibutylcarbitol)and Triton X-100 (noted E)from TM chloride media in 1,2-dichloroethane, toluene, chloroform and chlo-roform+toluene is quantitatively described. The extracted species are Co(PMBP)E whatever the aqueous electrolyte is (sodium, potassium, lithium and tetramethylammonium chloride) The extractions are compared to the ones performed with the crown-ethers 18C6 and DC18C6B.Keywords
