Definitions

  • FIGURE 6 illustrates the change of the BY2 concentration as a function of time for the adsorption of the cationic organic compound (of BY2) on the cross- linked composite membrane material at 25 °C.
  • FIGURE 7 illustrates the change of the AB74 concentration as a function of time for the adsorption of the anionic organic compound (of AB74) on the cross-linked composite membrane material at 25 °C.
  • the concentration of cationic BY2 dyestuff remaining in the aqueous solution decreases over time during the adsorption process.
  • the initial decrease amount is significantly higher.
  • the concentration of anionic AB74 dyestuff in an aqueous solution did not decrease during the adsorption process of 1440 minutes.
  • anionic AB74 dyestuff is not adsorbed by the cross-linked composite membrane. Therefore, while the cross-linked composite membrane shows a high affinity towards the cationic organic compound, its affinity towards the anionic organic compound is significantly lower.
  • Vacuum filtration method was employed in order to determine that which one of the dyestuffs is adsorbed better by the cross-linked composite membrane and which one of the dyestuffs is allowed to pass through the cross-linked composite membrane from an aqueous dyestuff mixture solution containing both the cationic BY2 dyestuff and the anionic AB74 dyestuff.
  • a piece of cross-linked composite membrane was cut suitable in size for the vacuum filtration apparatus and placed onto the filtration apparatus.
  • Nanofiltration composite membrane used for selective ion separation, and preparation method thereof Patent: CN108421422 (A). 6) Ratto, T.V. (2011) Membranes with embedded nanotubes for selective permeability, Patent: MX2011000140A.
