Abstract: A microextraction method, based on the complexation of Cu(II) with N-Benzoyl-N,Ndiisobutylthiourea, followed by phase separation by assistance of supramolecular solvents, was developed. The supramolecular solvent of tetrahydrofuran and 1-decanol enhanced the hydrogen bonding, in addition to the dispersion action leading to a quick phase separation with efficient preconcentration of copper(II) at trace levels. The developed procedure works at weak acidic medium (pH 3). The analytical parameters were optimized. …
