|Title||Preparation of Immobilized-Polysiloxane Salicylaldehyde Propylimine and Its Application|
A porous solid polysiloxane ligand system of the general formula P-(CH2) 3-C7H6NO,(where P represents [Si-O] n siloxane network) has been prepared by modification of the immobilized 3-aminopropylpolysiloxane, P-(CH2) 3NH2 with an exsess of salicylaldehyde. The new modified polysiloxane system exhibits good potential for uptake of Co 2+ and Cu 2+ metal ions. This ligand system gives more stable complexes with the divalent metal ions than its parent 3-aminopropylpolysiloxane precursor. Characterization was achieved using elemental analysis and FTIR spectroscopy.
