| Abstract | ||
| 2-[2-pyridil azo]-4-benzen naphthol [PABN] and 2-[(4-Hydroxy phenyl azo]-4,5- diphenyl imidazol [HPADPI] were Synthesized and used for the extraction of Zn(II) and Cd(II) from aqueous solutions. Effective factors on the extraction method was investigated stoichiometry shows the complex extracted was [M+2(PABN-(Cl-)] and [M+2(HPADPI)]2Cl- when (M2+=Zn2+,Cd2+), Thermodynamic studies appeared complexation reaction for Zn2+,Cd2+ with both organic reagents was endothermic, in addition of another studies. The research is apart of MSC thesis. | ||
