Sg. Tunina et al., Influence of supporting electrolyte cation on extraction of zinc with quinoline N-oxide from alkali metal bromide solutions, RUSS J G CH, 70(12), 2000, pp. 1867-1871
Extraction of zinc at 298 K with quinoline N-oxide from solutions of alkali
metal (Na+, K+, Rb+) bromides with the constant ionic strength (1, 1.5, 2,
3) supported by alkali metal nitrate was studied. The zinc extraction cons
tants and the stability constants of its bromide complexes at the given ion
ic strengths were calculated. A linear correlation was revealed between the
zinc extraction constant and the enthalpy of hydration of the supporting e
lectrolyte cation.
