Separation study of Mg+2 from seawater and RO brine through a facilitated bulk liquid membrane transport using 18-Crown-6
A facilitated bulk liquid membrane transport approach is studied for Mg(II) extraction from seawater and reversed osmosis brine simulated media using 18-Crown-6 and dibenzo (DB)-18-Crown-6. The work is based on investigating the experimental parameters affecting the transport efficiency, such as pH...

A facilitated bulk liquid membrane transport approach is studied for Mg(II) extraction from seawater and reversed osmosis brine simulated media using 18-Crown-6 and dibenzo (DB)-18-Crown-6. The work is based on investigating the experimental parameters affecting the transport efficiency, such as pH of feed and receiving phase, type of membrane solvent, temperature, type and concentration of the carrier, and stripping solution conditions. The transported amount of magnesium ions from feed phase (Mg(II) = 0.059 M, NaCl = 0.01 M, pH = 3.3) across a chloroform membrane (18C6 = 0.001 M) into the receiving phase (SCN− 0.1 M pH 3) was found to be %97 (±0.7) after 2.5 hr. The selectivity of the method was evaluated by performing competitive transport experiments on the mixtures containing Ca2+, Na+, K+, and Mg2+ ions. |
