Tannage Résumé : This article illustrates an experiment with the removal and recycling of Cr (VI) in a wastewater by the technique using an emulsion liquid membrane. The membrane solvent, the carriers and the types and amounts of stabiliser have been optimised. The liquid membrane recipe in optimal form is prepared as an emulsion to treat the water sample containing Cr (VI) so as to determine the effects of operating conditions, such as the pH of the internal and external water phase, the amount of carrier, the speed and the time of preparing the membrane, the membrane internal ratio and the emulsion water ratio. Note de contenu : - EXPERIMENTAL SECTION : Reagents and instrumentation - Experimental procedures - RESULTS AND DISCUSSION : Determination of experimental factors - Orthogonal experiment and results - Amount and type of carrier and the stability of the liquid membrane - Type and amount of surfactant and the stability of the Liquid Membrane - pH effects on the removal rate in the preliminary period of contact with the external water phase - Effects of the concentration of internal phase (NaOH) on the removal of Cr6+ - Effects of the Oil Internal Ratio on the Removal of Cr6+ - Effects of emulsion water rate on the removal of Cr6+ - Effects of stirring strength - Effects of stirring time - Table 1 : Orthogonal design factors and levels table - Table 2 : Results of the orthogonal experiment En ligne : https://drive.google.com/file/d/1QtbZVK5IwjJQsAfMB3iN8EQRWwTmQf4H/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=39782 [article]
