Industrial applications and environmental awareness recently prompted vanadium recovery spell from secondary resources. In this work, a polymer inclusion membrane containing trioctylmethylammonium chloride as carrier was successfully employed in electrodialysis for vanadium recovery from acidic sulfate solutions The permeability coefficient of V(V) increased from 0.29μm·s-1 (without elec. field) to 4.10μm·s-1 (with the 20 mA·cm-2 c.d.). The transport performance of VO2SO–4, which was the predominant species containing V(V) in the acidic region (pH <3), was influenced by the aqueous pH value and sulfate concentration Under an elec. field, a low concentrated H2SO4 solution (0.2 M) effectively stripped V(V) from the membranes, avoiding the requirement of a highly concentrated H2SO4 without elec. field. Under the optimum conditions, the permeability coefficient and flux reached 6.80μm·s-1 and 13.34μmol·m-2·s-1, resp. High selectivity was observed for the separation of V(V) and Mo(VI) from mixed solutions of Co (II), Ni (II), Mn (II), and Al (III). Addnl., the separation between Mo(VI) and V(V) was further improved by adjusting the acidity of the stripping solution The V(V) selectivity for the resulting membrane was higher than that of com. anion exchange membranes. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Safety of 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. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Safety of N-Methyl-N,N-dioctyloctan-1-aminium chloride
