原始语种摘要: Abstract(#br)Nuclear waste such as radioactive iodine has been received worldwide attention because of the effects of radiation on biological health. The efficient capture of radioactive iodine is of great importance for the safe utilization of nuclear energy. In this study, a functional porous organic polymer (P-TzTz) with high sulfur and nitrogen contents was synthesized by the catalyst-free hydrothermal process of dithiocarbanate (DTO) and benzo[1,2-b:3,4-b′:5,6-b″]trithiophene-2,5,8-tricarbaldehyde (BTT-THO) in N , N -dimethylformamide under N 2 atmosphere. This tailor-made amorphous polymer exhibits high affinity and adsorption capacity for iodine owing to its effective electron-rich sorption sites, π-conjugated structure and hierarchically porous structure. P-TzTz displays an...
