摘要

Abstract

A new chelating resin (CPS-DMA-SABA) was synthesized with the chloromethylated cross-linked polystyrene porous beads (CPS) as raw materials

which were bonded with salicylidene-o-aminobenzoic acid (SABA) on the surface via a quaternary ammonium unit as a linker. The results showed that CPS-DMA-SABA would easily change into a zwitterionic chelating resin (CPS-DMA-SABZ) when washed with distilled water. CPS-DMA-SABA was characterized by elemental analysis

infrared spectra and thermo-gravimetric analysis. The ion sorption capacities of CPS-DMA-SABA were found to be 1916 μg/g for Zn

with pH at 4.5

1620 μg/g for Cu

with pH at 6.2

1291 μg/g for Ni

with pH at 6.6 and 780 μg/g for Cr

with pH at 5.5

respectively. The experiments showed CPS-DMA-SABA also changed its color when meeting with the metal ion in the aqueous solution. As a consequence

CPS-DMA-SABA can not only be used as a solid phase extractant but also an indicator for confirming the heavy metal ion in solutions.
