اصطناع مرتبطة غير حلقية لأساس شيف من النمط N2S2 و تحديد مقدرتها الاستخلاصية للأيونات في الأوساط المائية

Abstract EN

An acyclic Schiff Base N-(4-methoxybenzylidene)-2-[2-(E)-2-(4-methoxybenzylideneamino) phenyl) disulfanyl] benzenamine (II)، containing nitrogen-sulfur donor atoms was synthesized by reaction of Bis(2-Aminophenyl) disulfide (I) with anisaldehyde and characterized.

The liquid-liquid extraction of transition metals picrate from aqueous phase to the organic phase was carried out using the novel ligand.

The effect of chloroform and dichloroethan as organic solvents on the metal extractions was investigated at 20oC by using UV-visible Spectrophotometry.

The influence of pH، ligand concentration، ionic strength، shaking time and ratio of aqueous-to-organic phases on extraction yield was tested at 20oC.

The extraction percent، distribution ratio and extraction constant of the tested metal ions were valuated.
