عنوان انگلیسی Simultaneous Extraction and Stripping of Methylene Blue: A Liquid-Liquid Extraction and Bulk Liquid Membrane Approach
چکیده انگلیسی مقاله In this study, the Liquid-Liquid Extraction (LLE) method was used to demonstrate the extraction of Methylene Blue (MB) from aqueous solutions using 4.48 ´10(-1) mol/L Phenyl Propiolic acid benzene. The operating parameters like the changes brought by varying pH (liquefied solution pH), diluents, the concentration of extractant, and stripping reagents were evaluated with fixed reaction conditions. A maximum recovery of MB was obtained at pH 7±0.1. Similarly, the maximum stripping efficiency of MB was achieved by the use of 1 N H2SO4. The optimized parameter obtained for the recovery of MB from the LLE process was implemented in the Bbulk Liquid Membrane (BLM) technique. The separation and procurement of MB were performed in a single step is called the protraction process. The role of pH in the aqueous donor phase, the effect of phenyl propiolic acid concentration in the membrane phase, and the effect of stripping reagents concentration were evaluated in detail to understand the transport mechanism of MB from the aqueous phase to interface and interface to stripping solution.
