a Permeance and b membrane selectivity for various dye molecules by the MPCM prepared with different reaction time. c UV–vis absorption spectra of the mixed dyes (methyl orange and Nile red) in methanol permeation through the MPCM. d UV–vis absorption spectra of the rhodamine B base in methanol permeation through the MPCM. (af membrane prepared with 2 wt% trianglamine). e Permeance of the membranes prepared with a 1 wt% aqueous phase concentration. f Solvents permeance through the membrane versus the solvent viscosity for the membrane prepared with 1 wt% trianglamine. All error bars represent the standard deviation for at least three independent measurements.
