Syntheses and characterization of a chelating resin containing ONNO donor quadridentate Schiff base and its coordination complexe with copper(II), nickel(II), iron(III), zinc(II), cadmium(II), molybde

摘要

A new mixed Schiff base N, N'-ethylenemono(3-carboxysaliclideneimine)mono(salicylideneimine) has been synthesized by the condensation of equimolar quantities of ethylenediamine, salicyladehyde and 3-formylsalicylic acid. A polymer supported Schiff base (PS-CH_2-LH_2) has been synthesized by the reasction of chloromethylated polystyrene (containing 3.9 mmol of chlorine per g of resin and 2/100 cross-linked with divinylbenzen) and the Schiff base N, N'-ethylenemono(3-carboxysalicylideneimine)mono(salicylideneimine).
