Extraction of the couple Zn2+ - Cd2+ by mixture of 1-phenyl-3-methyl-4-benzoylpyrazol-5-one and methylisobutylketone in toluene
Written by sctunisie no commentsThe extraction of the couple Zn2+ - Cd2+ from sulfate medium by mixture of 1-phenyl-3-methyl-4-benzoylpyrazol-5-one (HPMBP) and methyl isobutyl ketone (MIBK) in toluene has been studied. The theoretical approach of separation of couple metals appears in certain conditions the existence of mixed metals complexes. The results showed that mixed metals complexes have not been formed but showed a better Zn/Cd extraction selectivity.
