چکیده انگلیسی
Cloud point extraction (CPE) was used for Eu(III) determination in water samples using flame atomic absorption spectrometry (FAAS). Complex of Eu(III) with alizarin red S was extracted into the surfactant-rich phase of octylphenoxypolyethoxyethanol (Triton X-114) from samples at room temperature in presence of an amount of NaNO3. The parameters affecting CPE such as sample pH and concentrations of NaNO3, complexing agent and Triton X-114 were studied. Under the optimized conditions, the limit of detection (3σ) was 6 ng mL−1 and the relative standard deviation (RSD) was 1.95%. The method was successfully applied to Eu(III) determination in water samples.
