Tri alkyl ammonium hydrogen phthalate based ionic liquid has been explored for the efficient extraction of Zr and Hf from aqueous nitric acid solution During mass transfer Zr formed ZrL2(NO3)+ mono pos. species, which got exchanged with the single cations of the ionic liquid to maintain elec. neutrality in both phase. However, for Hf, the probable extracted species was ML(NO3)2+. The mass transfer processes were spontaneous, endothermic and driven by the entropic change in the systems. The D values for Zr were found to be more than that of the Hf due to more organophilicity of the complex. The significant changes in ligand functionalities: hydroxyl, carbonyl, -CO2 of carboxyl, -OH of carboxyl on complexation with Zr4+ were evidenced by FTIR spectra. Till 200 kGy gamma exposure, the ionic liquid was found to be rigid. No appreciable modification in ligand functionalities were evidenced by FTIR. However, up to 15% reduction in extraction performance was observed The EDXRF spectra of the functionalized ionic liquid after processing of simulated high-level waste showed the presence of U, Zr, Fe, Mn, Rh, Ni, Zn and Y along with minute contamination of Ca and Na. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Recommanded Product: N-Methyl-N,N-dioctyloctan-1-aminium chloride).
N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).Recommanded Product: N-Methyl-N,N-dioctyloctan-1-aminium chloride
