Polysulfone membrane sheet, PS (PS-20), (Sepro, California, CA, USA). Merck supplied 1,3-phenylenediamine (C6H8N2, 99.5%) and 1,3,5-benzenetricarbonyl trichloride (C9H3Cl3O3, 98%) (Kenilworth, New Jersey, NJ, USA). Short multiwalled carbon nanotubes (MWCNTs) with a purity of 95% and average diameter of 3–10 nm was provided by Grafen Chemical Industries (Ankara, Turkey). MWCNTs COOH and MWCNTs-NH2) are thin multiwalled carbon nanotubes that have been functionalized. MWCNT samples with a purity of 95% were obtained from Nanocyl (Sambreville, Belgium). Hexane (C6H14, 99%) was purchased from Oxford Laboratory (Mumbai, India). Sodium chloride (NaCl, 99%) was purchased from Sigma-Aldrich Chemicals (Hamburg, Germany), while anhydrous magnesium sulfate (MgSO4, 98%) and extra pure anhydrous sodium carbonate (Na2CO3, 99.5%) were obtained from Scharlau (Barcelona, Spain). Absolute ethanol (96%) was purchased from Ajax Finechem Pty, Ltd. (South Wales, Australia). Milli-Q® water (18.2) was used to make both solutions and dilutions in this study.
Anhydrous magnesium sulfate
Manufactured by Scharlab
Sourced in Germany, Spain
Anhydrous magnesium sulfate is a desiccant used to remove water from organic solvents and other liquids. It is a white, granular, and hygroscopic substance that can effectively absorb moisture from solutions.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
