Use of cyclopentyl methyl ether (CPME) as green membrane for acetic acid removal by facilitated bulk liquid membrane: A transport and kinetic study

In current investigation, cyclopentyl methyl ether (CMPE) was tested as a novel membrane solvent for acetic acid removal from an aqueous medium in the facilitated bulk liquid membrane (BLM). Tributyl phosphate (TBP) has been utilized as a carrier in CMPE to facilitate acetic acid transport. The influences of various operating factors like carrier concentration in the membrane solvent, receiving phase type, and receiving phase concentration on removal, were analyzed. The uptake was evaluated by means of feed (extraction) and receiving yields. Following this, a mass transfer modelling was established and the mass transfer coefficients were determined. The maximum yields were recorded as 95.4% for extraction and 78.01% for receiving yields at 2 mol & BULL; L-1 carrier concentration in membrane solvent, and 4 mol & BULL; L-1 NaOH of receiving phase concentration.
