Spectrophotometric determination of uranium in water samples after cloud point extraction using nonionic surfactant Triton X-114
A cloud point extraction process using the nonionic surfactant Triton X-114 to extracturanium from aqueous solutions was investigated. The method is based on the complexationreaction of uranium with Arsenazo III and micelle-mediated extraction of the complex. Theoptimal extraction and reaction conditions (e.g., pH, reagent concentration, effect of time) werestudied, and the analytical character...
متن کاملSimultaneous Determination of Carbazoles in Water Samples by Cloud Point Extraction Coupled to HPLC
Cloud point extraction (CPE) as a rapid, simple and efficient method coupled with high performance liquid chromatography (HPLC) was used for sample preparation and subsequent determination of carbazole, trinitrocarbazole (TrNC) and tetra nitro carbazole (TNC) in water samples. Some effective parameters on extraction, such as volume of Triton X-100, extraction time, extraction temperature, ionic...
متن کاملA Green Enrichment Method of Copper, Manganese and Nickel in Water Samples via Cloud Point Extraction
A new, cost-effective, and environmental-friendly cloud point extraction methodology was described for enrichment of copper, manganese and nickel in several water samples. The method involves the complexation of copper, manganese or nickel with 2-amino-6-(1,3-thiazol-2-diazeyl)-phenol at pH 7.0, then extraction into Triton X-114. After dilution of the surfactant-rich phase with acidified methan...
متن کاملThe Effect of Type and Concentration of Surfactant and Ligand on Uranium (VI) Cloud-Point Extraction (CPE) from Aqueous Solutions (Short Communication)
In this article cloud-point extraction (CPE) was used with chelating agent to extract uranium from aqueous solutions. The methodology used is based on the formation of metal complexes soluble in a micellar phase of surfactant. The metal ions complexes are then extracted into the surfactant-rich phase at a temperature above the cloud-point temperature. The effect of type of surfactants and ligan...
