The p- tertbutylcalix[4] arene tetracarboxylic acid( ] ), p- tertbutylcalix[6] arene hexacarboxylic acid (Ⅱ),and p- tertbutylcalix[8] arene octacarboxylic acid ( Ⅲ ) were synthesized. The extraction of Fe3+ using these calixarenes were investigated. The extraction mechanism was studied and the extraction equilibrium constants were determined. The possibility exclusing trace iron from rare- earth ions was also discussed.
