Nano-baskets of diacid p-tert-butylcalix[4]arene in the cone conformation were synthesized and used. The related parameters including ligand concentration, volume of water disperser, salt effect, and extraction time were optimized. The linear range, detection limit (S/N 3) and precision (RSD, n 6) were determined to be in the range of 1.0–280, 2.0–42.0 μgL−1 and 2.6– 11.0 %, respectively.
