  • primarily due to the particularly low content of PDA in the PCTA composite membrane, which significantly impacts the detection of PDA in NMR. The low concentration of PDA results in signal intensities that are much lower compared to the dominant signals from other components in the sample, such as CTA
  • . Although modern NMR instruments have improved sensitivity, there is still a practical detection threshold. If the concentration of PDA falls below this threshold, the signal may not be detectable or may be too weak to provide meaningful information. These factors make it challenging to detect and quantify
