[ 1 ] - Determination of Trace Amount of Zn2+ Ion in soil, blood and vegetable and water samples by Flame Atomic Absorption Spectrometry After Cloud Point Extraction Using Selective Synthesis Ligand2-(3- indolyl) – 4,5 di phynyl imidazole.
Abstract A simple, sensitive and feasible cloud-point extraction (CPE) methodology has been developed for the separation and preconcentration of cadmium and lead ions in real samples. The metals in the aqueous solution were complexes with 2-(3- indolyl) - 4,5 di phynyl imidazole.(IDPI), at pH = 7.0 and Triton X-114 was added as surfactant. The variables effecting like concentration of Triton ...
