Extraction Of Cobalt (II) Ions From Aqueous Medium Into Chloroform Solution Of 4-Propionyl-2,4-Dihydro-5- Methyl-2-Phenyl-3H-Pyrazol-3-One (HPrP): Effects Of pH, Acids And Complexing Agent:- Ukaeje, Joseph A

ABSTRACT

The extraction of Cobalt (II) ions from various buffered aqueous solutions was studied using chloroform solutions of 4-Propionyl-2, 4-dihydro-5-methyl-2- phenyl-3H-pyrazol-3-one (HPrP) Schiff base. The complexing agent and concentration effect of 4-propionyl-2, 4-dihydro5-methyl-2-phenyl-3H-pyrazol-3-one (HPrP) in these extractions certain mineral acids were examined alongside metal ions under a suitable extraction condition. From the mineral acids studied, cobalt didn’t form non extractable complex. Increase in pH above 10.0 resulted to a decrease in cobalt extraction. Increase in the concentration of various acids above 2.0 pushed the extraction. Increase in the concentration of various acids above 2.0 pushed thepercentage extraction to zero (0).
