Area of Science:

• Materials Science
• Environmental Chemistry
• Nuclear Chemistry

Background:

• Iodine contamination poses risks in various sectors, including the nuclear industry.
• Effective iodine capture materials are crucial for environmental remediation and safety.
• Existing methods for iodine removal can be inefficient or costly.

Purpose of the Study:

• To develop a novel, biocompatible cross-linked trianglamine network for efficient iodine removal.
• To evaluate the performance of this network in capturing iodine from vapor, water, and seawater.
• To assess the material's recyclability, cost-effectiveness, and scalability for industrial applications.

Main Methods:

• Synthesis of a biocompatible cross-linked trianglamine network.
• Testing iodine capture efficiency in the vapor phase.
• Evaluating iodine adsorption kinetics and capacity in aqueous solutions (water and seawater).
• Assessing the material's recyclability and stability.

Main Results:

• The cross-linked trianglamine network demonstrated high iodine capture capacity in the vapor phase (6 g g⁻¹).
• Efficient iodine removal was observed from both freshwater and seawater.
• The material exhibited fast adsorption kinetics and was fully recyclable.
• The study identified a high affinity between iodine and the trianglamine's intrinsic cavity.

Conclusions:

• The developed trianglamine network is a highly effective and versatile material for iodine capture.
• Its biocompatibility, cost-effectiveness, and scalability make it suitable for environmental and industrial applications, particularly in nuclear accident scenarios.
• This research highlights the potential of tailored porous materials for selective contaminant removal.
