Highly efficient, reversible iodine capture and exceptional uptake of amines in viologen-based porous organic polymers

Abstract

Viologen-based porous organic polymers as highly efficient and reversible adsorbents for iodine and amines.

Bisimidazole-Based Conjugated Polymers for Excellent Iodine Capture

“…However, the generation and proper disposal of radioactive waste are still an outstanding issue. The main components of nuclear waste are long-lived radioisotopes 133 I 2 , 131 I 2 , 129 I 2 , and 125 I 2 , which are volatile harmful species and are involved in human metabolic processes. − Therefore, how to effectively dispose of these nuclear wastes has become an important issue to be solved urgently. More recently, adsorption has been considered to be an effective method to capture iodine from liquids or gases, which has the advantages of simple equipment, convenient operation, a fast speed, a low cost, recyclability, and so on.…”

Ionic Functionalized Magnetic Porous Polymers as Advanced Materials for High-Efficiency Water Decontamination: Bactericidal and Iodine Adsorption

“…Previous reports have demonstrated that the I 2 adsorption capacity of an adsorbent was determined by the collective effects of the porosity, textural properties, and types of binding sites. For example, the electron-rich metallocene and benzene rings, high-polarity heteroatoms, metal atoms, and ionic groups can act as adsorption sites for iodine, significantly promoting the I 2 adsorption capacities through electrostatic and coulomb interactions. − FP-POP and iFP-POP were designed to combine multiple influencing factors.…”

“…Water is a resource essential for human survival, the pollution of which has always been a growing threat to the ecological balance. − Water contamination has become one of the most persistent global problems of public health. , Bacteria and radioactive iodine waste are the two common types of contaminants ubiquitously in water bodies that could cause devastating effects to public health. , Highly toxic radioactive iodine ( 129 I and 131 I) mainly generated from nuclear power plants with the feature of long half-life poses a serious threat to ecological security . Additionally, pathogenic bacteria, especially the appearance of antibiotic-resistant bacteria, in drinking water could lead to a series of infections in the digestive and respiratory systems of human beings and animals, leading to various diseases .…”

Fabrication of Polysulfone Beads Containing Covalent Organic Polymer as a Versatile Platform for Efficient Iodine Capture

“…Radioactive iodine in two isotopic forms, i.e., 129 I and 131 I, is considered a potential threat to the environment, animals, and human health. They are highly toxic, mobile, volatile, and soluble in aqueous media. , Moreover, exposure to 129 I and 131 I is also harmful because they can disturb the metabolic activities. Strictly speaking, if iodine isotopes are transferred into the human body through polluted air, contaminated food, water, etc., they can cause metabolic dysfunction and thyroid cancer due to abnormal function of the thyroid gland. − One common way employed in the adsorption of iodine vapor involves using liquid solutions.…”
