A 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 کاملSpectrophotometric 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 کاملSelective Cloud Point Extraction for the Spectrophotometric Determination of Cetylpyridinium Chloride in Pharmaceutical Formulations
In this work, we developed a simple and selective method for separation and spectrophotometric determination of trace amounts of cetylpyridinium chloride (CPC) in pharmaceutical products using cloud point extraction (CPE) technique. The method is based on cloud point extraction of the CPC in alkali conditions using of nonionic surfactant Triton X-114. Under selected conditions, the calibration ...
