Abstract
|
|
|
|
Chelating resins containing hydrazide or triethylenetetramine side chain were prepared using a commercial cation exchage resin, Diaion WK 11, and their nitrogen contents were determined by elemental analysis. The synthesized resin, and commercial chelating resins, (Diaion-CR 10 and-CR 20) were treated with various metal chelates of which metal contents were subsequently determined by chelatometry. Sectioned beads of the resin-metal chelates were also observed using electron microprobs X-ray analyzer. To examine the catalytic activity of the resin-metal chelates, they were applied to the oxidation of various hydroxy compounds and l-ascorbic acid, and found to be effective catalysts.
