摘要

The polymer supported metal complexes of N,N'-bis(acetyl acetone)o-phenylene-diamine (ACPDA) Schiff base were synthesized bysuspension copolymerization of styrene and allyl chloride in the presence of divinyl benzene (DVB) as cross-linker and azobisisobutyroni-trile (AIBN) as initiator at 70 ± 0.1°C and then ACPDA Schiff base and metal ions were loaded on the resulting polymer beads. The cross-linked density in polymer beads was varied by taking different concentrations of divinyl benzene in the reaction mixture. The polymer beadswere characterized for their cross-linked density, size (ф), density (p), degree of swelling (%S w) and loading of ACPDA Schiff base andmetal ions. The polymer beads prepared with 1.5 mmol of DVB (Type III) had a sufficient amount of allyl chloride (4.90 mmol,0.367 g) and showed optimum loading for ACPDA Schiff base (1.96 mmol g -1) and metal ions. The structures of copper(II) andiron(III) ions complexes (ACPDA-M) and their loading on polymer beads (P-ACPDA-M) was characterized with spectral analysis. Thecatalytic activity of unsupported and polymer supported ACPDA Schiff base complexes of copper(II) and iron(III) ions was evaluatedby studying the rate of decomposition of hydrogen peroxide.
