Compound: Tri-n-octylphosphine Oxide, is researched, Molecular C24H51OP, CAS is 78-50-2, about Green Emulsified Liquid Membrane for Hexavalent Chromium Extraction: Formulation and Process Optimization. Author is Anarakdim, Katia; Gutierrez, Gemma; Cambiella, Angel; Senhadji-Kebiche, Ounissa; Matos, Maria.
The influence of several formulation and operating conditions on hexavalent chromium extraction by green emulsified liquid membranes (GELMs) was studied. An excellent removal efficiency was achieved under optimized conditions. The optimum GELM formulation in terms of stability was obtained with tri-n-octylphosphine oxide (TOPO) as extractant, polyglycerol polyricinoleate (PGPR) and polyoxyethylene sorbitan monooleate (Tween 80) as stabilizers in sunflower oil. Optimum GELMs showed a monomodal distribution of sizes around 1.29μm. Results confimed that the use of a vegetable solvent and PGPR for GELM formulation is a promising alternative to petroleum organic solvents.
