“…Persistent organic pollutants are not only stable in natural waters but also traceable in animal and plant organisms over long periods of time. − Although the contaminants pose a major health risk and have been the subject of political action at the global level for decades, numerous toxins are detectable at high concentrations in groundwaters. ,, Several strategies have been reported for pollutant removal, such as adsorption, membrane separation, microbial degradation, advanced oxidation, enzymatic degradation, and so forth . Some of these methods were hindered by disadvantages like high costs, long process time, secondary pollution, and poor operability.…”

Using polymeric photocatalytic materials for visible lightdriven heterogeneous conversion of organic substances in environmentally benign reaction media as in water, in particular, has gained much attention recently. Most of the current conjugated polymer photocatalysts are often unsuitable for applications in water because of their highly hydrophobic nature. Classical polymer-based photocatalysts possess advantages that include precise control of properties through facile synthesis and direct access to the toolbox of classical polymer chemistry. However, the effect of monomer composition remains unclear, and a systematic investigation of structure−property relationships is still missing. In this work, we design water-compatible poly(methyl methacrylate) (PMMA)-based polymer photocatalysts by precise control of comonomers with specific functions. The electronic and optical properties and water compatibility of PMMA photocatalysts could be tuned, and they showed direct dependence on the monomer composition. Mathematical as well as density functional theory simulation as hydration enthalpy calculations supported the observed effects. The photocatalytic degradation of 2,4-dichlorophenol in water as model reaction showed an optimum of polymer composition and solubility for the photocatalytic reactivity. More remediation of important contaminants was successfully conducted as diethyl phthalate, acetophenone, and bisphenol-A, which are common products from plastic degradation detected in groundwater.

“…The use of membrane processes has provided promising results for a variety of separation applications, by offering undeniable advantages such as high efficiency and productivity, ease of operation and scale-up, and a small footprint [22][23][24][25]. Ultrafiltration (UF) is a low-pressure process that works based on the utilization of membranes with pores typically in the size range of 0.01-0.1 μm and has demonstrated very good performance for the removal of a wide range of micron-size impurities from aqueous streams [26][27][28].…”

Tailoring the Morphology and Performance of Polyacrylonitrile Ultrafiltration Membranes for Produced Water Treatment via Solvent Mixture Strategy

2022

The separation performance of membranes is highly dependent on their morphology and microstructure. The present study aims to tailor the characteristics of asymmetric polyacrylonitrile (PAN) ultrafiltration membranes by adopting a solvent mixture strategy, combining dimethylformamide (DMF) and N‐methyl‐2‐pyrrolidone (NMP) for produced water treatment. The ternary phase diagram was used for better analysis of the microstructural changes from the thermodynamics point of view. Using a solvent mixture containing more DMF (i.e., 75 %) and increasing the PAN concentration in the dope were effective in improving the solution viscosity and promoting delayed demixing. As a result, finger‐like macrovoids were suppressed to some extent and the internal morphology of the membranes was transformed into a sponge‐like structure, accompanied by a reduction in the overall membrane porosity and mean pore size.

“…The high osmotic pressure can cause a decline in the water flux when the concentration of ions in feed solution increases, which can limit the efficiency of fractionating organics from wastewaters . In that sense, fine-tuning the structure of the selective films to retain high water flux and superior rejection of organics have attracted great attention for the removal of dyes from industrial waste streams. − Composite membranes prepared using different piperazine-based derivatives, for example, demonstrated the influence of the diamine structure on the surface charge, morphology, and performance of the membrane . These membranes exhibited different rejection rates of mono- and multivalent ions with water permeance in the range 8.8–3.1 L m –2 h –1 bar –1 .…”

A naturally derived monomer, allylated gallic acid (AG), was herein proposed as a monomer for interfacially polymerized thin-film composite nanofiltration membranes. We investigated the synthesis of the thin-film composite polyester membranes by varying the concentration of the AG monomer and the reaction time with trimesoyl chloride. In addition, we demonstrated the synthesis of a polyesteramide film using a mixture of AG and m-phenylene diamine, although there are a few orders of magnitude differences in their reactivity. While membranes prepared using the classical polyamide process had a water permeance of 0.54 L m −2 h −1 bar −1 , the prepared polyesteramide and polyester films had water permeances of 12.3 and 47.6 L m −2 h −1 bar −1 , respectively The rejection of dyes was larger than 700 g mol −1 and could be tuned to 327 g mol −1 by changing the chemical composition and reaction time. The retention of inorganic salts followed the order Na 2 SO 4 > MgSO 4 ≈ NaCl. Therefore, the membrane performance demonstrates the potential of the phenolic monomer to be integrated into the synthesis of thin-film composite membranes. Besides, the availability of the free allyl group holds potential for further modification and covalent binding onto the surface.
