Application

  • Characterization and deployment of surface-engineered chitosan-triethylenetetramine nanocomposite hybrid nano-adsorbent for divalent cations decontamination: This research develops a chitosan-triethylenetetramine based nano-adsorbent for removing divalent cations from polluted sources, demonstrating its effectiveness in water treatment applications (Ali et al., 2020).
  • Highly Efficient and Reversible Absorption of SO2 by Aqueous Triethylenetetramine Tetralactate Solutions: A study focused on the use of triethylenetetramine for efficient and reversible absorption of sulfur dioxide, a significant environmental pollutant (Qian et al., 2014).
  • Multicavity triethylenetetramine-chitosan/alginate composite beads for enhanced Cr (VI) removal: This paper explores the synthesis of multicavity composite beads using triethylenetetramine for enhanced removal of chromium (VI) from contaminated water, showcasing a novel approach to heavy metal remediation (Zhang et al., 2019).
