英文摘要	3D polypyrrole (3D-PPy) monolith is prepared by a simple chemical oxidation of pyrrole monomer using FeCl3 as an oxidant. The as-prepared PPy monolith exhibits an abundant porosity and with a mesopore size of about 9.1 nm in diameter. Taking advantage of its mesoprous feature as well as the unique chemical composition, the 3D-PPy is employed as the porous medium for adsorption and removal of radioactive iodine from environment. A high iodine adsorption capacity of 1.6 g g(-1) for 3D-PPy is obtained which is competing with that of those reported porous organic polymers. Besides, the adsorption kinetics and adsorption thermodynamic experiments show that the adsorption is dominated by the pseudosecond-order kinetics and Langmuir models. Considering its simple and low cost-effective preparing method, unique monolithic porous as well as - conjugated chemical structure, the resulted 3D-PPy may be found useful applications for removal of radioactive iodine to address environmental issues.
