[ 1 ] - Sepration and determination trace amount of cadmium ions in real and water samples by cloud point extraction - flame atomic absorption spectrophotometry after preconcentration with non-ionic surfactant Triton-X114

2-(3- indolyl) – 4,5 di phynyl imidazole.(IDPI) was used as a complexing agent in cloud point extraction for the first time and applied for selective pre-concentration of trace amounts of cadmium. The method is based on the extraction of cadmium at pH= 7.0 by using non-ionic surfactant Triton-X114 and 2-(3- indolyl) – 4,5 di phynyl imidazole. (IDPI) as a chelating agent. The adopted concentrati...
