  1 - Copper concentration using micelle-mediated extraction in real samples
  Farshid Ahmadi Azadeh Khanmohammadi Ziba Tavakoli Jamshid Jafarpour
  A simple and sensitive method is described for the pre-concentration by cloud point extraction followed by atomic absorption spectrometric determination of copper ion in real samples. At a solution pH of 5.5, 5, 5-diphenylimidazolidine-2, 4-dione (phenytoin) (DFID) and أکثر

  A simple and sensitive method is described for the pre-concentration by cloud point extraction followed by atomic absorption spectrometric determination of copper ion in real samples. At a solution pH of 5.5, 5, 5-diphenylimidazolidine-2, 4-dione (phenytoin) (DFID) and TritonX-114 were used as hydrophobic ligand and non-ionic surfactant. The adopted concentrations for DFID, Triton X-114 and HNO3, bath temperature, centrifuge rate and time were optimized. Detection limits (3SDb/m) of 1.7 ng mL-1 along with enrichment factors of 35 for these ions were achieved. The proposed procedure was applied to the analysis of real samples. تفاصيل المقالة

  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 characteristics of the method (e.g., limit of detection, linear range)were obtained. Linearity was obeyed in the range of 1.0-150.0 ng mL-1 of U(IV) ion. Thedetection limit of the method was 0.3 ng mL-1 of uranium ion. The interference effect of someanions and cations was also tested. The method was applied to the determination of uranium inwater samples. تفاصيل المقالة
