Extraction and separation of mercury(II)‎ from succinate media with high molecular weight amine as an extractant

الملخص EN

The extraction of mercury(II) from succinate solutions by 2-octylaminopyridine (2-OAP) has been studied by metal distribution measurements.

The optimum extraction conditions were determined from a critical study of effects of pH, sodium succinate concentration and 2-octylaminopyridine concentration.

The probable composition of the species has been deduced from log–log plots.

The extraction reaction proceeds with ion-pair formation and the stoichiometry of extracted species was found to be [(2OAPH+)2 Hg(Succinate)2 2_](org).

The method has been used to separate mercury(II) from commonly associated elements.

The method has
