“…Saha and Joshi in their study on the influence of monomer types, concluded that an increase in MPDA concentration produces membranes with more free volume and tightness within the thin film, which in turn leads to higher flux and rejection, respectively [9]. In contrast to this study, Qiu's group found that an increase in the MPDA concentration level from 0.8 to 2.4% led to a decline in the membrane flux by 34% (from 780 to 520 l m −2 d −1 ) [8]. Thus, there does not seem to be a consensus on the influence of monomer concentrations on membrane properties and performance.…”

A B S T R A C TThis work describes a statistical study of the membrane formation reaction between 1,3-phenylene diamine (MPDA) and 1,3,5-benzenetricarbonyl trichloride (TMC) on polysulfone support. The membrane performance has been characterized in terms of water flux, salt passage, and intrinsic salt permeability, and the membranes were also characterized with respect to several structural and morphological factors. The ranges within which the concentration of each monomer was varied were chosen as being relevant to industrial practice, and this is borne out by the fact that the performance of the membranes formed is within the range of practical interest. This analysis reveals that the concentrations of MPDA and TMC significantly influenced the intrinsic salt permeability, water flux, and the characteristic properties of the active polyamide layer. Polynomial models have been derived for the performance parameters using response surface methodology, and allow an identification of monomer concentrations for optimal performance of the membrane.

“…In the case of PA TFC membranes, the influence of factors such as reaction time, additives, and physiochemical characteristics of base support membranes on flux and rejection are fairly well established in the literature [5][6][7][8]. However, the effect of monomer concentrations is still to be conclusively established.…”

A B S T R A C THollow-fiber composite nanofiltration (NF) membranes were prepared by interfacial polymerization method, polysulfone (PSF) hollow-fiber ultrafiltration membrane as base membrane. The effects of different dihydric alcohol in aqueous phase were mainly studied and optimized. Environmental conditions and reaction time on rejection and water flux of prepared composite NF membranes were also investigated. Furthermore, the morphology and chemical structure of composite membranes were examined by Fourier transform infrared spectroscopy (FT-IR), contact angle and scanning electronic microscopy (SEM), respectively.

“…Therefore, numerous research studies have been devoted to explore the underlying correlations between the synthesis parameters for the PA and desalination properties of the final TFCs. The most important parameters include the type and concentration of monomers and additives, organic solvents, reaction time, curing time and temperature, posttreatment strategies, and fabrication method of the PA layer …”

Optimizing synthesis factors of polyamide top layers is an important requirement in the design of thin film composite (TFC) membranes. In this research, the top layer fabrication method (conventional, heat curing, and spin coating), type of acid acceptor (sodium carbonate, sodium hydroxide, and triethylamine), type of organic phase solvent (hexane, heptane, and mixed hexane/heptane), and concentration of surfactant sodium dodecyl sulfate (0, 0.5, and 1 wt %) are selected as the control parameters of this synthesis and optimized using the Taguchi approach. The analysis of variance shows that the layer fabrication method is the most influential parameter on water flux and salt (NaCl) rejection of TFCs. Furthermore, although the type of organic solvent has not a significant contribution to the water flux, it is another significant factor affecting the rejection. The optimized membrane is then used to construct structureproperty relationships and to understand the influence of each individual factor on the desalination performance. Accordingly, a TFC membrane with the top layer fabricated by the heat curing method, in the presence of Na 2 CO 3 as the acid acceptor, hexane as the organic phase solvent and 0.5 wt % of the surfactant is prepared that shows water permeance of 2.73 L m −2 h −1 bar −1 and NaCl rejection of 98.1%. centration demonstrated the importance of these parameters in the preparation process of TFCs. The same group recently studied the synergistic effects of different additives on desalination properties of PA-TFC membranes. 23 The additives, which Additional Supporting Information may be found in the online version of this article.
